Abstract: A processing device collects depth data for frames in a sequence of images of a video stream being provided by a source device to a target device as part of a communication session. The depth data is created by a depth aware camera of the source device. The processing device maps, using the depth data, feature locations of the features of an object in a frame to feature locations of the features of the object in other frames, determines overlapping frame sections between the frames using the mapped feature locations, modifies, in the sequence of images, a set of images corresponding to the frames based on the overlapping frame sections to create a stabilized stream of images for the video stream, and provides the stabilized stream of images in the video stream as part of the communication session.

Abstract: Systems and methods are disclosed for gesture-initiated actions in videoconferences. In one implementation, a processing device receives content streams during a communication session, identifies a request for feedback within one of the content streams, based on an identification of the request for feedback, processes the content streams to identify one or more gestures within at least one of the content streams, and based on a determination that a first gesture of the one or more gestures is relatively more prevalent across the content streams than one or more other gestures, initiates an action with respect to the communication session.
