| description | A video background processing system is disclosed that is configured to receive a video stream including a plurality of successive first video frames at a first resolution. The system comprises a video resolution modifier configured to reduce the resolution of the first video frames from the first resolution to a second resolution lower than the first resolution and thereby generate second video frames. The system also comprises a foreground determiner configured to determine a foreground portion and a background portion in the second video frames and to produce first foreground data indicative of locations of the foreground and background portions in the second video frames at the second resolution, wherein the foreground determiner is configured to use the first foreground data to generate second foreground data indicative of locations of the foreground and background portions in the first video frames. The system also comprises a compositor circuit configured to use replacement background content and the second foreground data to generate combined video frames at the first resolution, each combined video frame including the foreground portion from a first video frame and the replacement background content. A corresponding method is also disclosed. |
