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: Implementations generally relate to enhancing content appearance. In some implementations, a method includes receiving an image, selecting a reference object in the image. The method also includes determining one or more image parameter adjustments based on the selected reference object, and applying the one or more image parameter adjustments to the entire image.

Abstract: A method and computing system for receiving an indication of a first user participating in a videoconference. A determination is made concerning whether bandwidth compression is preferable for the first user of the videoconference. If bandwidth compression is preferable for the first user of the videoconference: an unprocessed video stream associated with the first user is processed to generate a reduced bandwidth video stream, and the reduced bandwidth video stream is provided to a video encoder. Processing the unprocessed video stream includes performing an edge detection procedure on the unprocessed video stream.
