Determination of the number of single-directional and double-directional motion compensation image boxes to be coded for a video sequence and detection of scene clips in the video sequence

摘要

A method of detecting scene cuts in a video sequence comprised of a plurality of frames, the method comprising: computing motion vectors for a first frame and a second frame in the plurality of frames; determining a motion cost value for the computed motion vectors of the first frame and the second frame; determining a ratio between the motion cost value for the computed motion vectors of the first frame and the motion cost value for the computed motion vectors of the second frame; and determining if there is a scene cut between the first frame and the second frame based on the ratio.
