Video data reduction by selected frame elimination

摘要

In a video processing system selected frames are eliminated to reduce the amount of video data. The frames are selected for elimination by scoring the frames to determine which frames can be eliminated and then most easily recreated from the remaining video after the elimination has taken place. When frames are eliminated, residuals are produced representing the difference between the recreated frames and the corresponding original frames which were eliminated. The frame elimination and generation of residuals is carried out in repeated cycles to progressively reduce the size of the remaining video until the amount of data in the computed residuals for each frame in the reduced video equals or exceeds the amount of data in the corresponding frames.
