Abstract: The technical problem of creating an augmented reality (AR) experience that, on one hand, is accessible from a camera view user interface provided with a messaging client and that, also, can perform a modification based on a previously captured image of a user, is addressed by providing an AR component. When a user, while accessing the messaging client, engages a user selectable element representing the AR component in the camera view user interface, the messaging system loads the AR component in the messaging client. The AR component comprises a target media content object, which can be animation or live action video. The loaded AR component accesses a portrait image associated with a user and modifies the target media content using the portrait image. The resulting target media content object is displayed in the camera view user interface.

Abstract: Provided are systems and methods for customizing modifiable videos. An example method includes analyzing recent messages associated with a user in a multimedia messaging application to determine a context of the recent messages, determining, based on the context, a property of a modifiable feature, selecting, based on the context, a list of relevant modifiable videos from a database configured to store modifiable videos associated with a preset modifiable feature, replacing a property of the preset modifiable feature in relevant modifiable videos of the list of relevant modifiable videos with the property of the modifiable feature, and rendering the list of relevant modifiable videos for viewing by the user, where the rendering includes displaying the modifiable feature in the relevant modifiable videos.

Abstract: Disclosed are systems and methods for single image-based body animation. An example method includes receiving an input image, the input image including a body image of a person, extracting the body image of the person from the input image, fitting a generic model to the body image, where the generic model is configured to receive a set of pose parameters corresponding to a pose of the person and generate a generic body shape adopting the pose, generating a three-dimensional (3D) model, where the 3D model is configured to receive a set of further pose parameters corresponding to the pose of the person and generate an output image of the person adopting the pose, the output image including a feature of the body image being omitted from the generic body shape, and providing a further set of further pose parameters to generate a frame of an output video.

Abstract: The subject technology captures first image data by a computing device, the first image data comprising a target face of a target actor and facial expressions of the target actor, the facial expressions including lip movements. The subject technology generates, based at least in part on frames of a source media content, sets of source pose parameters. The subject technology receives a selection of a particular facial expression from a set of facial expressions. The subject technology generates, based at least in part on sets of source pose parameters and the selection of the particular facial expression, an output media content. The subject technology provides augmented reality content based at least in part on the output media content for display on the computing device.

Abstract: Provided are systems and methods for animating a single image of a human body and applying effects. An example method includes providing a database of motions; receiving an input image including a body of a person; receiving a user input including a motion selected from the database of motions; segmenting the input image into a body portion and a background portion; fitting the body portion to a hair model; generating, based on the body portion and the selected motion, a video featuring the body of the person repeating the selected motion; where generating the video includes detecting positions of key points associated with a head of the person in a frame of the video, generating an image of hair of the person based on the positions of the key points and the hair model, and inserting the image of the hair in the frame; and displaying the generated video.

Abstract: Provided are systems and methods for realistic head turns and face animation synthesis. An example method may include receiving frames of a source video with the head and the face of a source actor. The method may then proceed with generating sets of source pose parameters that represent positions of the head and facial expressions of the source actor. The method may further include receiving at least one target image including the target head and the target face of a target person, determining target identity information associated with the target face, and generating an output video based on the target identity information and the sets of source pose parameters. Each frame of the output video can include an image of the target face modified to mimic at least one of the positions of the head of the source actor and at least one of facial expressions of the source actor.

Abstract: Provided are systems and methods for photorealistic real-time portrait animation. An example method includes receiving a scenario video with at least one input frame. The input frame includes a first face of a first person. The method further includes receiving a target image with a second face of a second person. The method further includes determining, based on the at least one input frame and the target image, two-dimensional (2D) deformations of the second face and a background in the target image. The 2D deformations, when applied to the second face, modify the second face to imitate at least a facial expression and a head orientation of the first face. The method further includes applying the 2D deformations to the target image to obtain at least one output frame of an output video.

Abstract: Provided are systems and a method for photorealistic real-time face reenactment. An example method includes receiving a target video including a target face and a scenario including a series of source facial expressions, determining, based on the target face, one or more target facial expressions, and synthesizing, using the parametric face model, an output face. The output face includes the target face. The one or more target facial expressions are modified to imitate the source facial expressions. The method further includes generating, based on a deep neural network, a mouth region and an eyes region, and combining the output face, the mouth region, and the eyes region to generate a frame of an output video.
