Abstract
Automatic adaptive zoom enables computing devices that receive video streams to use a higher resolution stream when the user enables zoom, so that the quality of the output video is preserved. In some examples, a tracking video stream and a target video stream are obtained and are processed. The tracking video stream has a first resolution, and the target video stream has a second resolution that is higher than the first resolution. The tracking video stream is processed to define regions of interest for frames of the tracking video stream. The target video stream is processed to generate zoomed-in regions of frames of the target video stream. A zoomed-in region of the target video stream corresponds to a region of interest defined using the tracking video stream. The zoomed-in regions of the frames of the target video stream are then provided for display on a client device.
