CONTEXTUAL GESTURE-BASED IMAGE SEARCHING

Abstract

Performing an image search on a mobile device, initiated through an issuance of contextual gestures on a touch screen by the user. A user opens a photograph, issues a gesture on that photograph via the touch screen. The gesture generates a search query looking for photographs that match the criteria of that search query indicated by the gesture. For example by issuing a pinching gesture on a photograph of a person's mouth the user can search for photographs of that person where they are smiling. The gestures may be emotion-based, time-based, or size-based contextual gestures, and utilizes cognitive image analysis for locating appropriate photographs.

Description

BACKGROUND

The present invention relates to contextual gesture-based image searching, and more specifically to contextual gesture-based image searching on devices with a touch interface.

Photography on mobile devices continues to gain popularity. Mobile device users are building up large repositories of photographs taken on these devices. In addition, the popularity of photo sharing social networks are increasing the number of photographs stored online. Providing intuitive methods to search these large repositories is becoming ever more important.

Advancements in cognitive techniques and object recognition enable deep analysis into what a photograph is showing. Additionally social networks add tags to photographs. Therefore, for a given photograph it is possible to tell who is in a photograph, what emotion is portrayed on their face, when and where the photograph was captured, and many other factors.

Existing solutions for image searching can use gestures. While each has slight differences, the main theme is for a user to select an object in a photograph by either tapping the photo or circling a portion of the photo with a gesture, then identifying other instances of photographs where that object also appears.

Of course, network data processing system 51 also may be implemented as a number of different types of networks, such as, for example, an intranet, local area network (LAN), or a wide area network (WAN). FIG. 1 is intended as an example, and not as an architectural limitation, for the different illustrative embodiments.

FIG. 2 illustrates internal and external components of a device computer 52 and server computer 54 in which illustrative embodiments may be implemented. In FIG. 1, a device computer 52 and a server computer 54 include respective sets of internal components 800a, 800b and external components 900a, 900b.

Alternatively, the functions of a contextual gesture search program 66 can be implemented in whole or in part by computer circuits and other hardware (not shown).

FIG. 7 shows a flowchart of a method of cognitive analysis of images for creation of a content aware image repository.

In a first step, an identification of a repository of electronic images for cognitive analysis is received (step 702), for example by the contextual gesture search program 66. The repository 67, 53 may consist of photographs stored: locally on a mobile device 52; cloud-based such as a social network account, or other repositories.

The images within the identified repository are analyzed to determine and extract any metadata of the images (step 704) and to determine the content within the images (step 706), by the contextual gesture search program 66.

Tags are associated with the images based on the identified content and metadata (step 708), for example by the contextual gesture search program 66. The repository is updated (step 710) and the method ends.

Cognitive techniques can be used to build up metadata and tags describing the content of the images in the identified repository. AlchemyVision® employs deep learning to understand a picture's content and context. This can determine factors such as who is in frame, their gender and age, and high level tags about their surroundings. Visual Recognition determines and understands the contents of image to create classifiers which identify objects, events, and settings. The cognitive techniques may be combines with existing metadata associated with a photograph (such as information stored in an exchangeable image file format (EXIF) metadata as social tagging) and stored in a repository. This metadata includes fields such as: date of capture; location of capture; identified people; identified facial expressions; and identified objects.

FIG. 8 shows a flowchart of a method of contextual gesture based image searching.

In a first step, the contextual gesture search program 66 receives a user selection of an image to display on a touchscreen of a device, to the user (step 802).

The image is displayed to the user on the touchscreen of the device (step 804).

The contextual gesture search program 66 receives gestures on an image via the touchscreen from the user (step 806). This gesture indicates the type of image search to be performed.

Gestures can be pre-defined by the system, and can be customized by the user so that a specific gesture performs a specific search. When the user issues a gesture the system records the following information: the gesture issued (for example: pinching gesture) and the location of the gesture (for example: XY coordinates).

The gesture issued is identified through analyzation of the gesture and the location of the gesture on the image (step 808). The system calculates the gesture issued by determining what is located in the image at the location of the issued gesture.

There are different types of image based searching that occurs relative to the gesture issued and the associated context of the image.

An emotion based search gesture is a gesture which is received by the system over the face of a person within the image. For example a pinching motion over the mouth of a person indicates a command to perform a search for other images, where this person is expressing an emotion of sadness. An upward motion gesture over an eye indicates to search for photographs of this person looking surprised.

FIG. 3a shows an example of a user issuing a contextual gesture to search for images for a subject smiling The issued gesture is an expanding gesture (indicated by outward arrows 304) between two fingers 302, 303 of the user, with the user moving their fingers 302, 303 away from each other over the mouth 305 of a person 306 (shown as cartoon) within the image. Based on the contextual gesture received, the contextual gesture search program 66 searches for other images of the same person smiling. It should be noted that these searches can be used with photographs of people. FIG. 3b shows an example of a search result of the search initiated by the user in FIG. 3a. This gesture can also be associated with a search for the emotion of happy as shown in FIG. 4a.

FIG. 4b shows an example of an emotion search gesture for the emotion of sad. The issued search gesture is pinching (indicated by inwards arrows 307) between two fingers 302, 303 of the user on a mouth 305 of a person 306 within the image. Based on the contextual gesture received, the contextual gesture search program 66 searches for other images of the same person who is sad.

FIG. 4c shows an example of an emotion search gesture for the emotion of surprised. The issued search gesture is an expanding gesture (indicated by outward arrows 311) between two fingers 302, 303 of the user, with the user moving their fingers away from each other over at least one eye 310 of a person 306 within the image. Based on the contextual gesture received, the contextual gesture search program 66 searches for other images of the same person who is surprised.

FIG. 4d shows an example of an emotion search gesture for the emotion of upset. The issued search gesture is a pinching gesture (indicated by inwards arrows 312) between two fingers 302, 303 of the user, with the user moving their fingers 302, 303 towards each other over at least one eye 310 of a person 306 within the image. Based on the contextual gesture received, the contextual gesture search program 66 searches for other images of the same person who is upset.

The contextual search of emotions is not limited to the examples given above. Additional emotions may be searched for and defined by the user or predefined by the system. Furthermore, while the examples referenced searching for people displaying emotions, the search may apply to animals or other objects displaying emotions, such as inanimate objects or computer-generated people.

A time-based search gesture is gesture performed over a person or an object within an electronic image. The time-based search gesture allows a user to search for images of a person which are older or younger (see FIGS. 5a and 5b) or an earlier or later version of an object (see FIGS. 5c and 5d).

FIG. 5a shows an example of a time-based search gesture for older images. The issued search gesture is an expanding gesture (indicated by outward arrows 313) between two fingers 302, 303 of the user, with the user moving their fingers 302, 303 away from each other over the person 315 within the image. Based on the contextual gesture received, the contextual gesture search program 66 searches for other images of the same person 315 which are older than the current image of the person.

FIG. 5b shows an example of a time-based search gesture for younger images. The issued search gesture is pinching (indicated by inward arrows 314) between two fingers 302, 303 of the user on the person 315 within the image, with the user bringing their fingers 302, 303 together. Based on the contextual gesture received, the contextual gesture search program 66 searches for other images of the same person 315 which are younger than the current image of the person.

FIG. 5c shows an example of a time-based search gesture for an earlier image. The issued search gesture is a leftward gesture (indicated by arrows 316) by the user's fingers 302, 303 over the object 317 in the image, which in this case is building. Based on the contextual gesture received, the contextual gesture program 66 searches for other images of the object 317 which are earlier than the object in the image. In the example of object in the image being a building, an earlier picture of the building may be during construction versus the finished building.

Similarly, FIG. 5d shows an example if a time-based search gesture for a later image. The issued search gesture is a rightward gesture (indicated by arrows 320) over the object 317 in the image, which in this case is building. Based on the contextual gesture received, the contextual gesture program 66 searches for other images of the object 317 which are earlier than the object currently displayed in the image. In the example of object in the image being a building, a later picture of the building may be the finished building versus a picture of the building under construction, in which the issued gesture was received on.

A size-based search gesture is a gesture performed over an object for different sizes of the object.

For example, FIG. 6a shows an example of a size based search gesture for a larger image. The issued search gesture is an expanding gesture (indicated by outward arrows 321) between two fingers 302, 303 of the user, with the user moving their fingers 302, 303 away from each other over the object 318 within the image. Based on the contextual gesture received, the contextual gesture search program 66 searches for other images of the object 318 which are larger than the object in the current image.

FIG. 6b shows an example of a size based search gesture for a smaller image. The issued search gesture is pinching (indicated by inward arrows 322) between two fingers 302, 303 of the user on the object 318 within the image, with the user bringing their fingers together. Based on the contextual gesture received, the contextual gesture search program 66 searches for other images of the object 318 which are smaller than the object in the current image.

The contextual gesture search program 66 performs an image search within at least one repository for the identified gesture (step 810) and the results are displayed to the user (step 812) and the method ends.

The repository which is searched may be a content aware image repository in which the images were pre-analyzed for content. The repository is preferably created using the method of FIG. 7. The content aware image repository 67 contains metadata and tags for each photograph within that repository. In this instance the system performs a simple search, using the criteria indicated by the user with their gesture to search the metadata and associated tags. For example, the contextual search program 66 may search for images of the Empire State Building within a user's personal device or social network user profile which are older than the current image being displayed on the user's device.

Alternatively or in addition to the content aware image repository 53, other image repositories may also be searched. For example, the contextual search program 66 in addition to or alternatively may search for pictures of the Empire State Building taken before 2016 in a public image repository.

The results of the search may be presented to the user through a touchscreen display of the user's device 52. The images corresponding to the results of the search may be presented as image thumbnails which the user can select to view full size. The user can indicate which images from the search they prefer or most match their criteria, and this preference can be taken into account when the user issues future image searches.

The creation of the content aware image repository 67 decreases the resources required for the processor to conduct an image search and thus increases the speed in which a processor of the user's device can conduct such a search.
