Abstract
During a video conference, a bandwidth reduction affecting a conference participant represented by a video stream without a virtual background is detected. Based on the bandwidth reduction, the video stream is segmented into a background and a foreground, in which the foreground depicts the conference participant. A resolution of the background is decreased while maintaining a resolution of the foreground. An adjusted video stream including the background at the decreased resolution and the foreground at the maintained resolution is then transmitted for rendering within a user interface of the video conference. Accordingly, portions of a video stream depicting a conference participant can be maintained at an initial quality level while adjusting other portions of the video stream to address network issues affecting a computing device of the conference participant.
