The present disclosure is generally related to the field of animated representation of human subjects in immersive reality applications. More specifically, the present disclosure is related to generating a three-dimensional (3D) stylized representation of a subject to add expressive content and eliminate artifacts in the immersive reality experience.
Conventionally, artificial reality, extended reality, or extra reality (collectively “XR”) is a form of reality that has been adjusted in some manner before presentation to a user, which may include, e.g., virtual reality (VR), augmented reality (AR), mixed reality (MR), hybrid reality, or some combination and/or derivatives thereof. Artificial reality content may include completely generated content or generated content combined with captured content (e.g., real-world photographs). The artificial reality content may include video, audio, haptic feedback, or some combination thereof, any of which may be presented in a single channel or in multiple channels (such as stereo video that produces a three-dimensional effect to the viewer).
Current models for human representation tend to have artifacts and gaps, which reduces an element of verisimilitude and liveliness desirable to bridge the gap across human representation in VR/AR applications.
The subject disclosure provides for systems and methods for generating stylized representations. One aspect of the present disclosure, the method includes retrieving a two-dimensional (2D) image of a subject and a depth field associated with the 2D image, generating a three-dimensional (3D) mesh based on the 2D image and the depth field, generating a stylized texture field based on an analysis of the 2D image of the subject, and generating a 3D stylized model of the subject by enveloping the 3D mesh with the stylized texture field.
Another aspect of the present disclosure relates to a system configured for generating stylized representations. The system includes one or more processors, and a memory storing instructions which, when executed by the one or more processors, cause the system to perform operations. The operations include to retrieve a 2D image of a subject, generate a depth field associated with the 2D image of the subject, generate a 3D mesh based on the 2D image and the depth field, generate a stylized texture field based on an analysis of the 2D image of the subject, and generate a 3D stylized model of the subject by enveloping the 3D mesh with the stylized texture field.
Yet another aspect of the present disclosure relates to a non-transient computer-readable storage medium having instructions embodied thereon, the instructions being executable by one or more processors to perform a method(s) for generating stylized representations described herein. The method may include retrieving a 2D image of a subject, generating a depth field associated with the 2D image of the subject, generating a 3D mesh based on the 2D image and the depth field, generating a stylized texture field based on an analysis of the 2D image of the subject, wherein the stylized texture field is a 2D representation of texture properties identified in the 2D image of the subject, and generating a 3D stylized model of the subject by enveloping the 3D mesh with the stylized texture field.
These and other embodiments will be evident from the present disclosure. It is understood that other configurations of the subject technology will become readily apparent to those skilled in the art from the following detailed description, wherein various configurations of the subject technology are shown and described by way of illustration. As will be realized, the subject technology is capable of other and different configurations and its several details are capable of modification in various other respects, all without departing from the scope of the subject technology. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not as restrictive.
In the figures, elements having the same or similar reference numerals are associated with the same or similar attributes, unless explicitly stated otherwise.
In the following detailed description, numerous specific details are set forth to provide a full understanding of the present disclosure. It will be apparent, however, to one ordinarily skilled in the art, that the embodiments of the present disclosure may be practiced without some of these specific details. In other instances, well-known structures and techniques have not been shown in detail so as not to obscure the disclosure.
Embodiments of the disclosed technology may include or be implemented in conjunction with an artificial reality system. Artificial reality, extended reality, or extra reality (collectively “XR”) is a form of reality that has been adjusted in some manner before presentation to a user, which may include, e.g., virtual reality (VR), augmented reality (AR), mixed reality (MR), hybrid reality, or some combination and/or derivatives thereof. Artificial reality content may include completely generated content or generated content combined with captured content (e.g., real-world photographs). The artificial reality content may include video, audio, haptic feedback, or some combination thereof, any of which may be presented in a single channel or in multiple channels (such as stereo video that produces a three-dimensional (3D) effect to the viewer). Additionally, in some implementations, artificial reality may be associated with applications, products, accessories, services, or some combination thereof, that are, e.g., used to create or generate content (such as models and other virtual representations) in an artificial reality and/or used in combination with a user's environment. The artificial reality system that provides the artificial reality content may be implemented on various platforms, including a head-mounted display (HMD) connected to a host computer system, a standalone HMD, a mobile device or computing system, a “cave” environment or other projection system, or any other hardware platform capable of providing artificial reality content to one or more viewers.
In the field of virtual reality (VR) and augmented reality (AR) applications, 3D representations of human (e.g., avatars) subjects are a computationally intensive task that may lead to gaps and artifacts which detract from the verisimilitude of the application. Additionally, from the point of view of expression, while progress has been steady with holograms and codec avatars, there is still a long way to go to achieve a desired fidelity. Real-time avatars are difficult to render with both self-expression and social presence. Even in cases where fidelity is satisfactory, it may be desirable to enhance some aspects and features of a subject, to add dramatism and emotional depth to a given scene.
Embodiments, as disclosed herein, address a problem in traditional artificial representation techniques tied to computer technology, namely, the technical problem(s) of generating realistically stylized models/representations in immersive reality applications. Embodiments are able to render more expressive avatars by taking aspects of a photorealistic representations and stylizing them (e.g., making representations more animated). The disclosed system solves this technical problem by providing a solution also rooted in computer technology, namely, by providing a pretrained stylistic neural network (NN) model designed to generate representations based on captured inputs. The disclosed subject technology further provides improvements to the functioning of the computer itself because it reduces the degree of complexity in texture mapping, and it improves processing, efficiency, and verisimilitude in artificial reality applications.
According to embodiments, stylized models are overlayed on a 3D mesh generated by a representation pipeline based on the stylistic NN model. The representation pipeline receives a two-dimensional (2D) input (e.g., live video feed or captured images, uploaded images, or content, etc.). The stylistic NN model may be a 2D-based algorithm including a generative adversarial network (GAN) applied to recreate stylized texture maps according to a desired stylistic training and envelope a 3D mesh forming a hologram with the texture maps.
In some embodiments, the stylistic NN model training may be based on a desired depiction style of the human figure (e.g., cartoons, a given artistic “school” or epoque). Once the model is trained, the degree of complexity of these texture maps is lower, thus enabling seamless real-time representations. The generated representations may be visually realistic and appear human-like.
In some embodiments, the generated representations may effectively represent emotions, expressivity, and appearance based on a subject(s) in an input image, and as such effectively communicates intent of the user through the representation. Expressivity may be conveyed via poses of a body and/or face of the generated representation through animated behaviors translating the subject's personality/emotions.
In some implementations, representations may be generated based on a moving subject (e.g., a user captured in real time at a client device). To patch gaps and inconsistencies resulting from subject motion or change of a direction of view, some embodiments include a buffering technique that superimposes several frames as the subject moves to correct for missing data on any one of the frames.
Client devices 110 may include any one of a laptop computer, a desktop computer, or a mobile device such as a smart phone, a palm device, or a tablet device. In some embodiments, client devices 110 may include a headset for virtual reality (VR) applications, or a smart glass for augmented reality (AR) applications, or other wearable device, such that at least one participant may be running an immersive reality messaging platform installed therein. In that regard, the headset or smart glass may be paired to a smart phone for wireless communication with an AR/VR application installed in the smart phone, and from the smart phone, the headset or smart glass may communicate with server 130 via network 150.

For example, client device 110 may provide a data packet (e.g., dataset 225) to server 130 including an image of the user. Accordingly, server 130 may provide to client device 110 a data packet (e.g., dataset 225) including a 3D representation based on the image of the user.

In some embodiments, memory 220-2 includes an application engine 232. Application engine 232 may share or provide features and resources to GUI 224, including multiple tools associated with training and using a stylistic model for generating stylistic representations in immersive reality applications. The user may access application engine 232 through application 222 installed in a memory 220-1 of client device 110. Accordingly, application 222 may be installed by server 130 and perform scripts and other routines provided by server 130 through any one of multiple tools. Execution of application 222 may be controlled by processor 212-1. Application engine 232 may include one or more modules configured to perform operations according to aspects of embodiments.

In some embodiments, the first device 302 captures a video from which one or more frames are extracted to generate a single 2D representation frame of the person.
A 3D mesh 310 is generated based on a depth scan of the image 304. In some embodiments, the 2D, RGB frame is combined with the depth scan captured at the user device to generate the 3D mesh 310.
At process image 306, the image 304 is processed using the stylistic model 308 to generate stylized textures 312. The stylized textures 312 are 2D, stylized fields indicative of a texture property of the captured images. The stylistic model 308 generates stylized texture fields per RGB frame (e.g., image 304).
The stylized textures 312 are projected onto the 3D mesh 310 to generate a stylized 3D representation 314 of the subject having a stylized look. Expressions and emotions may be conveyed via poses of a body and/or face of the stylized 3D representation 314 based on the subject and animations and textures applied in accordance with the pre-trained model. In some embodiments, the stylized textures 312 are projected onto the 3D mesh 310 to generate a hologram. The hologram may be based on a set of images (e.g., RGB pixelated, 2D array) or a video collection and a depth scan of the subject. The stylized 3D representation 314 may be generated based on the hologram.
According to embodiments, the first device 302 may be capturing a moving subject. This may be at least one cause of artifacts in the hologram or stylized 3D representation 314. In order to combat this issue, artifacts in the hologram or stylized 3D representation 314 may be identified. A buffer may be applied to areas of the hologram or stylized 3D representation 314 identified as containing artifacts. The buffer may act as a texture patching layer for the areas with artifacts.

The identifying module 660 is configured to identifying discontinuities (e.g., artifacts) in the stylized texture field.
The buffering module 670 is configured to buffer the 3D stylized model and patch the discontinuities in the stylized texture field to generate a texture modified 3D stylized model. In some implementations, the system 600 may be further configured to determine whether the subject is moving resulting in discontinuities in at least one of the stylized texture field or the 3D stylized model. When the subject is determined to be moving, the buffering module 670 may be further configured to path by the discontinuities superimposing multiple, consecutive two-dimensional images of the subject as the subject moves.
The outputting module 680 is configured to output a display of the 3D stylized model (or similarly, the modified 3D stylized model) to a second client device. The output may be a projection of the 3D stylized model in a virtual space or real space. In some implementations, the first and second client devices are the same device associated with an AR/VR application. In some implementations, the first device is a device (e.g., mobile device or computer) separate from the second device (e.g., a VR/AR headset).

To illustrate the interchangeability of hardware and software, items such as the various illustrative blocks, modules, components, methods, operations, instructions, and algorithms have been described generally in terms of their functionality. Whether such functionality is implemented as hardware, software, or a combination of hardware and software depends upon the particular application and design constraints imposed on the overall system. Skilled artisans may implement the described functionality in varying ways for each particular application.
As used herein, the phrase “at least one of” preceding a series of items, with the terms “and” or “or” to separate any of the items, modifies the list as a whole, rather than each member of the list (i.e., each item). The phrase “at least one of” does not require selection of at least one item; rather, the phrase allows a meaning that includes at least one of any one of the items, and/or at least one of any combination of the items, and/or at least one of each of the items. By way of example, the phrases “at least one of A, B, and C” or “at least one of A, B, or C” each refer to only A, only B, or only C; any combination of A, B, and C; and/or at least one of each of A, B, and C.
To the extent that the term “include,” “have,” or the like is used in the description or the claims, such term is intended to be inclusive in a manner similar to the term “comprise” as “comprise” is interpreted when employed as a transitional word in a claim. The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.
A reference to an element in the singular is not intended to mean “one and only one” unless specifically stated, but rather “one or more.” All structural and functional equivalents to the elements of the various configurations described throughout this disclosure that are known or later come to be known to those of ordinary skill in the art are expressly incorporated herein by reference and intended to be encompassed by the subject technology. Moreover, nothing disclosed herein is intended to be dedicated to the public regardless of whether such disclosure is explicitly recited in the above description. No clause element is to be construed under the provisions of 35 U.S.C. § 112, sixth paragraph, unless the element is expressly recited using the phrase “means for” or, in the case of a method clause, the element is recited using the phrase “step for.”
While this specification contains many specifics, these should not be construed as limitations on the scope of what may be claimed, but rather as descriptions of particular implementations of the subject matter. Certain features that are described in this specification in the context of separate embodiments can also be implemented in combination in a single embodiment. Conversely, various features that are described in the context of a single embodiment can also be implemented in multiple embodiments separately or in any suitable subcombination. Moreover, although features may be described above as acting in certain combinations and even initially claimed as such, one or more features from a claimed combination can in some cases be excised from the combination, and the claimed combination may be directed to a subcombination or variation of a subcombination.
The subject matter of this specification has been described in terms of particular aspects, but other aspects can be implemented and are within the scope of the following claims. For example, while operations are depicted in the drawings in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed, to achieve desirable results. The actions recited in the claims can be performed in a different order and still achieve desirable results. As one example, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In certain circumstances, multitasking and parallel processing may be advantageous. Moreover, the separation of various system components in the aspects described above should not be understood as requiring such separation in all aspects, and it should be understood that the described program components and systems can generally be integrated together in a single software product or packaged into multiple software products. Other variations are within the scope of the following claims.
The present disclosure is related and claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Application No. 63/378,436, filed on Oct. 5, 2022, to Christopher John OCAMPO et al., entitled STYLIZING REALISTIC HUMAN REPRESENTATIONS IN VR/AR APPLICATIONS, the contents of which are hereby incorporated by reference, in their entirety, for all purposes.
