Image and video captions are an important tool for providing context, telling stories, and enhancing engagement with media content in the context of social media. However, manually creating captions can be time consuming and difficult to scale across large volumes of user-generated content.
Conventional solutions have relied on manual data entry, predefined template captions, or simple mapping of metadata like time and location to generate basic captions automatically. These approaches lack the advanced artificial intelligence needed to analyze visual contents of an image or video and produce an engaging, relevant caption tailored to the specific people, objects, and scenery depicted.
Recent advances in computer vision, natural language processing, and machine learning have demonstrated increasing sophistication in processing visual information and generating natural language descriptions. Powerful deep learning techniques can now detect objects, extract semantic information, and synthesize written text that is coherent and matches the input data.
However, existing AI caption generation technology has yet to provide the accuracy, contextual adaptation, and creative flair needed for captions that enhance media experiences and provide value to end users. There is a need for caption generation capabilities that combine state-of-the-art AI with user-centric design to create captions personalized to both content and individual preferences. The present disclosure aims to address this need through techniques for automated media captioning using artificial intelligence.

The present disclosure describes systems and methods for automatically generating captions for images and videos using artificial intelligence techniques. The process involves receiving an image or video from a user device, then analyzing the pixels and contents using computer vision algorithms to detect people, objects, scenery, and other elements depicted.
The objects and entities detected in the image or video are used to generate a prompt that summarizes the key visual components. This prompt is provided to a natural language processing (NLP) model that outputs one or more caption options relevant to the detected objects/entities. A natural language processing model is an artificial intelligence (AI) based system trained to understand, interpret, and generate human language.
According to certain embodiment, an NLP model may be trained on large datasets of natural language examples like books, articles, websites, transcripts, and social media posts, wherein the training data exposes the model to vocabulary, grammar, writing conventions, content, and other attributes of human language. For example, in some embodiments, the system may compile a database of training data that includes: a large dataset of images paired with human-written captions that describe the contents, wherein the captions serve as ground truth targets during training; captions that incorporate contextual factors like location, time of day, user demographics, etc, wherein the contextual factors may train the model to integrate contextual information; images paired with multiple diverse captions highlighting different aspects of the image to emphasize model variety; images paired with captions in different tones/styles like funny, formal, sarcastic in order to train the model on stylistic language; images paired with captions localized into different languages; images and captions collected from different geographic regions and cultural contexts to train on cultural diversity; images depicting a wide range of scenes, objects, activities, etc., to train the model on generalizability; images from social media sites to match real-world distributions; facial recognition annotations on images to identify people and their emotions; object, scene, and activity labeling of image contents to supplement pixel data. After sufficient training, the NLP model may ingest inputs that include image data in order to produce relevant text outputs.
In some embodiments, the system can further enhance the prompt by incorporating contextual information associated with the media, such as the time, location, or user profile data. This allows generating captions adapted to the user's context, such as mentioning the beach when the photo was taken at a beach location.
In some embodiments, the user can provide an input to select a desired tone or style for the captions, such as funny, serious, or sarcastic. The prompt can reflect this selected tone so the language model generates caption options in an appropriate style.
The generated captions are ranked using various relevance, diversity, and quality metrics. The highest ranking captions are displayed to the user in order from best to worst. The presentation interface may show captions overlaid on the image/video itself, in a separate display pane, or through a rotating carousel with one caption shown at a time.
Additional techniques include allowing the user to tap or select a specific object in order to generate captions focused on describing just that object rather than the entire image. The user can also initiate generation using a graphical icon rather than manually entering text.
Underlying the system are deep learning models for computer vision and natural language processing. Multi-task training techniques are employed to train the models jointly and maximize performance. Safety mechanisms are utilized to sanitize the computer vision outputs and avoid generating inappropriate or offensive captions.
In summary, the present disclosure provides an AI-powered solution for automatically creating captions customized to the image/video contents and tailored to the end user's context and preferences. The system combines computer vision, natural language processing, and deep learning to enhance media experiences through automated caption generation.
A messaging client 108 is able to communicate and exchange data with another messaging client 108 and with the server system 104 via the network 102. The data exchanged between messaging client 108, and between a messaging client 108 and the server system 104, includes functions (e.g., commands to invoke functions) as well as payload data (e.g., text, audio, video or other multimedia data).
The server system 104 provides server-side functionality via the network 102 to a particular messaging client 108. While certain functions of the system 100 are described herein as being performed by either a messaging client 108 or by the server system 104, the location of certain functionality either within the messaging client 108 or the server system 104 may be a design choice. For example, it may be technically preferable to initially deploy certain technology and functionality within the server system 104 but to later migrate this technology and functionality to the messaging client 108 where a client device 106 has sufficient processing capacity.
The server system 104 supports various services and operations that are provided to the messaging client 108. Such operations include transmitting data to, receiving data from, and processing data generated by the messaging client 108. This data may include message content, client device information, geolocation information, media augmentation and overlays, message content persistence conditions, social network information, and live event information, as examples. Data exchanges within the system 100 are invoked and controlled through functions available via user interfaces (UIs) of the messaging client 108.
Turning now specifically to the server system 104, an Application Program Interface (API) server 112 is coupled to, and provides a programmatic interface to, application servers 110. The application servers 110 are communicatively coupled to a database server 116, which facilitates access to a database 122 that stores data associated with messages processed by the application servers 110. Similarly, a web server 124 is coupled to the application servers 110, and provides web-based interfaces to the application servers 110. To this end, the web server 124 processes incoming network requests over the Hypertext Transfer Protocol (HTTP) and several other related protocols. In certain embodiments, the database 122 may include a decentralized database.
The Application Program Interface (API) server 112 receives and transmits message data (e.g., commands and message payloads) between the client device 106 and the application servers 110. Specifically, the Application Program Interface (API) server 112 provides a set of interfaces (e.g., routines and protocols) that can be called or queried by the messaging client 108 in order to invoke functionality of the application servers 110. The Application Program Interface (API) server 112 exposes various functions supported by the application servers 110, including account registration, login functionality, the sending of messages, via the application servers 110, from a particular messaging client 108 to another messaging client 108, the sending of media files (e.g., images or video) from a messaging client 108 to a messaging server 114, and for possible access by another messaging client 108, the settings of a collection of media data (e.g., story), the retrieval of a list of friends of a user of a client device 106, the retrieval of such collections, the retrieval of messages and content, the addition and deletion of entities (e.g., friends) to an entity graph (e.g., a social graph), the location of friends within a social graph, and opening an application event (e.g., relating to the messaging client 108).
The application servers 110 host a number of server applications and subsystems, including for example a messaging server 114, an image processing server 118, and a Social network server 120. The messaging server 114 implements a number of message processing technologies and functions, particularly related to the aggregation and other processing of content (e.g., textual and multimedia content) included in messages received from multiple instances of the messaging client 108. As will be described in further detail, the text and media content from multiple sources may be aggregated into collections of content (e.g., called stories or galleries). These collections are then made available to the messaging client 108. Other processor and memory intensive processing of data may also be performed server-side by the messaging server 114, in view of the hardware requirements for such processing.
The application servers 110 also include an image processing server 118 that is dedicated to performing various image processing operations, typically with respect to images or video within the payload of a message sent from or received at the messaging server 114.
The Social network server 120 supports various social networking functions and services and makes these functions and services available to the messaging server 114. Examples of functions and services supported by the Social network server 120 include the identification of other users of the system 100 with which a particular user has relationships or is “following,” and also the identification of other entities and interests of a particular user.
The ephemeral timer system 202 is responsible for enforcing the temporary or time-limited access to content by the messaging client 108 and the messaging server 114. The ephemeral timer system 202 incorporates a number of timers that, based on duration and display parameters associated with a message, or collection of messages (e.g., a story), selectively enable access (e.g., for presentation and display) to messages and associated content via the messaging client 108. Further details regarding the operation of the ephemeral timer system 202 are provided below.
The collection management system 204 is responsible for managing sets or collections of media (e.g., collections of text, image video, and audio data). A collection of content (e.g., messages, including images, video, text, and audio) may be organized into an “event gallery” or an “event story.” Such a collection may be made available for a specified time period, such as the duration of an event to which the content relates. For example, content relating to a music concert may be made available as a “story” for the duration of that music concert. The collection management system 204 may also be responsible for publishing an icon that provides notification of the existence of a particular collection to the user interface of the messaging client 108.
The collection management system 204 furthermore includes a curation interface 208 that allows a collection manager to manage and curate a particular collection of content. For example, the curation interface 208 enables an event organizer to curate a collection of content relating to a specific event (e.g., delete inappropriate content or redundant messages). Additionally, the collection management system 204 employs machine vision (or image recognition technology) and content rules to automatically curate a content collection. In certain examples, compensation may be paid to a user for the inclusion of user-generated content into a collection. In such cases, the collection management system 204 operates to automatically make payments to such users for the use of their content.
The augmentation system 206 provides various functions that enable a user to augment (e.g., annotate or otherwise modify or edit) media content associated with a message. For example, the augmentation system 206 provides functions related to the generation and publishing of media overlays for messages processed by the system 100. The augmentation system 206 operatively supplies a media overlay or augmentation (e.g., an image filter) to the messaging client 108 based on a geolocation of the client device 106. In another example, the augmentation system 206 operatively supplies a media overlay to the messaging client 108 based on other information, such as social network information of the user of the client device 106. A media overlay may include audio and visual content and visual effects. Examples of audio and visual content include pictures, texts, logos, animations, and sound effects. An example of a visual effect includes color overlaying. The audio and visual content or the visual effects can be applied to a media content item (e.g., a photo) at the client device 106. For example, the media overlay may include text or image that can be overlaid on top of a photograph taken by the client device 106. In another example, the media overlay includes an identification of a location overlay (e.g., Venice beach), a name of a live event, or a name of a merchant overlay (e.g., Beach Coffee House). In another example, the augmentation system 206 uses the geolocation of the client device 106 to identify a media overlay that includes the name of a merchant at the geolocation of the client device 106. The media overlay may include other indicia associated with the merchant. The media overlays may be stored in the database 122 and accessed through the database server 116.
In some examples, the augmentation system 206 provides a user-based publication platform that enables users to select a geolocation on a map and upload content associated with the selected geolocation. The user may also specify circumstances under which a particular media overlay should be offered to other users. The augmentation system 206 generates a media overlay that includes the uploaded content and associates the uploaded content with the selected geolocation.
In other examples, the augmentation system 206 provides a merchant-based publication platform that enables merchants to select a particular media overlay associated with a geolocation via a bidding process. For example, the augmentation system 206 associates the media overlay of the highest bidding merchant with a corresponding geolocation for a predefined amount of time.
The map system 210 provides various geographic location functions, and supports the presentation of map-based media content and messages by the messaging client 108. For example, the map system 210 enables the display of user icons or avatars on a map to indicate a current or past location of “friends” of a user, as well as media content (e.g., collections of messages including photographs and videos) generated by such friends, within the context of a map. For example, a message posted by a user to the system 100 from a specific geographic location may be displayed within the context of a map at that particular location to “friends” of a specific user on a map interface of the messaging client 108. A user can furthermore share his or her location and status information (e.g., using an appropriate status avatar) with other users of the system 100 via the messaging client 108, with this location and status information being similarly displayed within the context of a map interface of the messaging client 108 to selected users.
The game system 212 provides various gaming functions within the context of the messaging client 108. The messaging client 108 provides a game interface providing a list of available games that can be launched by a user within the context of the messaging client 108, and played with other users of the system 100. The system 100 further enables a particular user to invite other users to participate in the play of a specific game, by issuing invitations to such other users from the messaging client 108. The messaging client 108 also supports both the voice and text messaging (e.g., chats) within the context of gameplay, provides a leaderboard for the games, and also supports the provision of in-game rewards (e.g., coins and items).
The captioning system 214 provides automated generation of captions for images and videos. In some embodiments, the captioning system 214 receives media files from client devices. Computer vision algorithms analyze the media contents to detect people, objects, scenery, and other visual elements. Based on the detected entities, the captioning system 214 generates descriptive prompts summarizing the media contents. The prompts are input to natural language processing models which output caption text. The captioning system 214 the captions and provides a presentation interface to end users, allowing toggling between options. Additional operations include sanitizing outputs, streamlining generation requests, and sharing media with captions through social platforms.
Operation 302 comprises receiving image or video data from a client device 106. The data can depict a wide variety of real-world scenes and contexts. Images may include photos of people, animals, objects, scenery, text, events, selfies, group shots, nature, man-made structures, or other subject matter. Videos may include scenes with motion, camera pans, multiple individuals, audio, and diverse environments. The data can be received by the captioning system 214 over a network 102. The data may originate from smartphone cameras, digital cameras, video cameras, downloads, screen recordings, or other capture and storage devices known in the art.
Operation 304 comprises detecting objects depicted in the received media, such as people, animals, objects, scenery, text, gestures, expressions, etc. In some embodiments, techniques like YOLO, Mask R-CNN, and other segmentation and object detection models known in the art are used. The models are trained on diverse labeled image datasets encompassing millions of samples.
Operation 306 comprises generating a descriptive prompt summarizing the key components and objects detected in the media. For example, the prompt can incorporate contextual data like location, time, and user profile information. In some embodiments, the prompts comprise natural language strings digestible by downstream language models.
Operation 308 comprises providing the prompt to a natural language processing model associated with the captioning system 214. The models are fine-tuned on media caption datasets to generate relevant captions based on the prompts.
Operation 310 comprises generating caption text based on the prompt and language model outputs. Multiple caption options are generated to provide alternatives to the user.
Operation 312 comprises displaying the generated captions to the user via interfaces like overlays, side-by-side panes, rotating carousels, and other presentation formats known in the art. Users can toggle between options to select desired captions.
At operation 402, the captioning system 214 accesses contextual data at the client device 106 responsive to operation 302 of the method 300 wherein the captioning system 214 receives image data from the client device 106. According to certain embodiments, the contextual data can include many factors associated with the media capture context. Examples include: location data such as GPS coordinates, place names, maps metadata, etc. that indicates where the media was captured; temporal data such as timestamps, day/time, calendar data that indicates when the media was captured; user profile data such as name, age, gender, interests, social connections that indicates who captured the media, or in some embodiments who is depicted within the image data; device sensor data such as orientation, motion, speed, acceleration, ambient light levels that indicate how the media was captured; application context such as a current session state associated with the client device 106; and search queries, browsing history, recent app usage that indicates additional user context.
At operation 404, the captioning system 214 generates a prompt to be provided to a natural language processing model, that incorporates selected contextual data in addition to describing the identified objects/entities. This allows tailoring the prompt to the specific time, place, person, and other context for more personalized, relevant captions. The contextual data can provide useful hints to the language model on top of the core visual contents.
At operation 502, the captioning system 214 receives an input from the client device 106 that selects or otherwise identifies a desired tone or style for the generated captions. For example, the tone may be selected based on a selection of a graphical icon or identifier that corresponds with each tone, may be based on an input received from the client device 106 that indicates the desired tone, or in some embodiments may be determined based on image features of the image data and one or more contextual factors associated with the client device 106. As an illustrative example, the tones may include one or more of: funny; sarcastic; formal; romantic; inspirational; descriptive; and conversational. Accordingly, each tone may correspond with a string to be included in the prompt provided by the captioning system 214 to the natural language processing model.
At operation 504, the captioning system 214 generates a prompt that incorporates words, phrasing based on the selected caption tone. This guides the language model to generate captions with the appropriate style and language.
Interface 602 includes a display of image data 608, and a display of a set of graphical icons 610. The image data 608 may include a photo or video provided by the user that contains various visual features detectable by the system's computer vision algorithms.
In some embodiments, the graphical icons 610 correspond with various function performed by the captioning system 214, such as automated caption generation. Accordingly, a user of the client device 106 may provide an input to select a graphical icon from among the graphical icons 610 in order to cause the captioning system 214 to generate one or more captions based on the image data 608, and one or more contextual factors.
As seen in the interface 604, upon activation of an automated caption generation feature of the captioning system 214, the system may cause display of a graphical icon 612 that indicates a style of one or more captions being produced. In some embodiments, and as discussed in the method 500 depicted in
Interface 606 provides an illustration of an output caption 614 provided by the captioning system 214, wherein a highest ranking caption 614 is overlaid at a position upon the image data 608. In some embodiments, captions are ranked using relevance, diversity, and quality metrics. From the candidate set, the top caption 616 among a plurality of generated captions is shown to the user first. Additional taps allow cycling through other generated captions. A user may thereby select a caption generated by the captioning system 214 in order to generate media content based on the selected caption and the image data 608.

The libraries 810 can also include a wide variety of other libraries 828 to provide many other APIs to the applications 806.
The frameworks 808 provide a common high-level infrastructure that is used by the applications 806. For example, the frameworks 808 provide various graphical user interface (GUI) functions, high-level resource management, and high-level location services. The frameworks 808 can provide a broad spectrum of other APIs that can be used by the applications 806, some of which may be specific to a particular operating system or platform.

Various programming languages can be employed to create one or more of the applications 806, structured in a variety of manners, such as object-oriented programming languages (e.g., Objective-C, Java, or C++) or procedural programming languages (e.g., C or assembly language). In a specific example, the third-party application 840 (e.g., an application developed using the ANDROID™ or IOS™ software development kit (SDK) by an entity other than the vendor of the particular platform) may be mobile software running on a mobile operating system such as IOS™, ANDROID™, WINDOWS® Phone, or another mobile operating system. In this example, the third-party application 840 can invoke the API calls 850 provided by the operating system 812 to facilitate functionality described herein.

For example, a network or a portion of a network may include a wireless or cellular network and the coupling may be a Code Division Multiple Access (CDMA) connection, a Global System for Mobile communications (GSM) connection, or other types of cellular or wireless coupling. In this example, the coupling may implement any of a variety of types of data transfer technology, such as Single Carrier Radio Transmission Technology (1×RTT), Evolution-Data Optimized (EVDO) technology, General Packet Radio Service (GPRS) technology, Enhanced Data rates for GSM Evolution (EDGE) technology, third Generation Partnership Project (3GPP) including 3G, fourth generation wireless (4G) networks, Universal Mobile Telecommunications System (UMTS), High Speed Packet Access (HSPA), Worldwide Interoperability for Microwave Access (WiMAX), Long Term Evolution (LTE) standard, others defined by various standard-setting organizations, other long-range protocols, or other data transfer technology.
“Component” refers to a device, physical entity, or logic having boundaries defined by function or subroutine calls, branch points, APIs, or other technologies that provide for the partitioning or modularization of particular processing or control functions. Components may be combined via their interfaces with other components to carry out a machine process. A component may be a packaged functional hardware unit designed for use with other components and a part of a program that usually performs a particular function of related functions. Components may constitute either software components (e.g., code embodied on a machine-readable medium) or hardware components. A “hardware component” is a tangible unit capable of performing certain operations and may be configured or arranged in a certain physical manner. In various example embodiments, one or more computer systems (e.g., a standalone computer system, a client computer system, or a server computer system) or one or more hardware components of a computer system (e.g., a processor or a group of processors) may be configured by software (e.g., an application or application portion) as a hardware component that operates to perform certain operations as described herein. A hardware component may also be implemented mechanically, electronically, or any suitable combination thereof. For example, a hardware component may include dedicated circuitry or logic that is permanently configured to perform certain operations. A hardware component may be a special-purpose processor, such as a field-programmable gate array (FPGA) or an application specific integrated circuit (ASIC). A hardware component may also include programmable logic or circuitry that is temporarily configured by software to perform certain operations. For example, a hardware component may include software executed by a general-purpose processor or other programmable processor. Once configured by such software, hardware components become specific machines (or specific components of a machine) uniquely tailored to perform the configured functions and are no longer general-purpose processors. It will be appreciated that the decision to implement a hardware component mechanically, in dedicated and permanently configured circuitry, or in temporarily configured circuitry (e.g., configured by software), may be driven by cost and time considerations. Accordingly, the phrase “hardware component” (or “hardware-implemented component”) should be understood to encompass a tangible entity, be that an entity that is physically constructed, permanently configured (e.g., hardwired), or temporarily configured (e.g., programmed) to operate in a certain manner or to perform certain operations described herein. Considering embodiments in which hardware components are temporarily configured (e.g., programmed), each of the hardware components need not be configured or instantiated at any one instance in time. For example, where a hardware component comprises a general-purpose processor configured by software to become a special-purpose processor, the general-purpose processor may be configured as respectively different special-purpose processors (e.g., comprising different hardware components) at different times. Software accordingly configures a particular processor or processors, for example, to constitute a particular hardware component at one instance of time and to constitute a different hardware component at a different instance of time. Hardware components can provide information to, and receive information from, other hardware components. Accordingly, the described hardware components may be regarded as being communicatively coupled. Where multiple hardware components exist contemporaneously, communications may be achieved through signal transmission (e.g., over appropriate circuits and buses) between or among two or more of the hardware components. In embodiments in which multiple hardware components are configured or instantiated at different times, communications between such hardware components may be achieved, for example, through the storage and retrieval of information in memory structures to which the multiple hardware components have access. For example, one hardware component may perform an operation and store the output of that operation in a memory device to which it is communicatively coupled. A further hardware component may then, at a later time, access the memory device to retrieve and process the stored output. Hardware components may also initiate communications with input or output devices, and can operate on a resource (e.g., a collection of information). The various operations of example methods described herein may be performed, at least partially, by one or more processors that are temporarily configured (e.g., by software) or permanently configured to perform the relevant operations. Whether temporarily or permanently configured, such processors may constitute processor-implemented components that operate to perform one or more operations or functions described herein. As used herein, “processor-implemented component” refers to a hardware component implemented using one or more processors. Similarly, the methods described herein may be at least partially processor-implemented, with a particular processor or processors being an example of hardware. For example, at least some of the operations of a method may be performed by one or more processors 1004 or processor-implemented components. Moreover, the one or more processors may also operate to support performance of the relevant operations in a “cloud computing” environment or as a “software as a service” (SaaS). For example, at least some of the operations may be performed by a group of computers (as examples of machines including processors), with these operations being accessible via a network (e.g., the Internet) and via one or more appropriate interfaces (e.g., an API). The performance of certain of the operations may be distributed among the processors, not only residing within a single machine, but deployed across a number of machines. In some example embodiments, the processors or processor-implemented components may be located in a single geographic location (e.g., within a home environment, an office environment, or a server farm). In other example embodiments, the processors or processor-implemented components may be distributed across a number of geographic locations.
“Computer-readable storage medium” refers to both machine-storage media and transmission media. Thus, the terms include both storage devices/media and carrier waves/modulated data signals. The terms “machine-readable medium,” “computer-readable medium” and “device-readable medium” mean the same thing and may be used interchangeably in this disclosure.
“Ephemeral message” refers to a message that is accessible for a time-limited duration. An ephemeral message may be a text, an image, a video and the like. The access time for the ephemeral message may be set by the message sender. Alternatively, the access time may be a default setting or a setting specified by the recipient. Regardless of the setting technique, the message is transitory.
“Machine storage medium” refers to a single or multiple storage devices and media (e.g., a centralized or distributed database, and associated caches and servers) that store executable instructions, routines and data. The term shall accordingly be taken to include, but not be limited to, solid-state memories, and optical and magnetic media, including memory internal or external to processors. Specific examples of machine-storage media, computer-storage media and device-storage media include non-volatile memory, including by way of example semiconductor memory devices, e.g., erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), FPGA, and flash memory devices; magnetic disks such as internal hard disks and removable disks; magneto-optical disks; and CD-ROM and DVD-ROM disks The terms “machine-storage medium,” “device-storage medium,” “computer-storage medium” mean the same thing and may be used interchangeably in this disclosure. The terms “machine-storage media,” “computer-storage media,” and “device-storage media” specifically exclude carrier waves, modulated data signals, and other such media, at least some of which are covered under the term “signal medium.”
“Non-transitory computer-readable storage medium” refers to a tangible medium that is capable of storing, encoding, or carrying the instructions for execution by a machine.
“Signal medium” refers to any intangible medium that is capable of storing, encoding, or carrying the instructions for execution by a machine and includes digital or analog communications signals or other intangible media to facilitate communication of software or data. The term “signal medium” shall be taken to include any form of a modulated data signal, carrier wave, and so forth. The term “modulated data signal” means a signal that has one or more of its characteristics set or changed in such a matter as to encode information in the signal. The terms “transmission medium” and “signal medium” mean the same thing and may be used interchangeably in this disclosure.
