Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media relate to a method for training machine learning network to generate facial expression for rendering an avatar within a video communication platform representing a video conference participant. Video images may be processed by the machine learning network to generate facial expression values. The generated facial expression values may be modified or adjusted to change the facial expression values. The modified or adjusted facial expression values may then be used to render a digital representation of the video conference participant in the form of an avatar.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media related to multi-stream video encoding for screen sharing a communications session. The system may determine a sub-area and a remaining area of a display region. A first video stream of the sub-area is generated at a first frame rate. A second video stream of the remaining area is generated at second frame rate, where the second frame rate is a frame rate lower than the first frame rate. A client device may transmit the first video stream and the second video stream to a second client device.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media related to multi-stream video encoding for screen sharing a communications session. The system may determine an active pixel area and a remaining pixel area of a video region. of a video region. A first video stream of the active pixel area is generated at a first frame rate. A second video stream of the remaining pixel area is generated at second frame rate, where the second frame rate is a frame rate lower than the first frame rate. A client device may transmit the first video stream and the second video stream to a second client device.

Abstract: Methods and systems provide for video appearance adjustments within a video communication session. First, the system receives video content. The system then receives an appearance adjustment request comprising an adjustment depth, and detects imagery of a user within the video content. The system then detects a face region within the video content. The system segments the face region into a number of skin areas. For each of the plurality of skin areas, the system classifies the skin area as a smooth texture region or rough texture region. If the skin area is classified as a smooth texture region, the system modifies the imagery of the user in real time or substantially real time by applying a smoothing process to the skin area, where the amount of smoothing applied corresponds to the adjustment depth.

Abstract: A best available video stream is determined for each of multiple conference participants within a conference room including multiple cameras based on scores determined for video streams obtained from the cameras. The scores are determined based on representations of the conference participants within the video streams, for example, based on percentages of conference participant faces visible within the video streams, directions of conference participant faces relative to the cameras, directions of eye gaze of the conference participants relative to the cameras, and/or degrees to which conference participant faces are obscured within the video streams. The best available video streams are output for rendering within separate user interface tiles of conferencing software.
