Abstract: The traditional methods of video synopsis need completely decoding video in pixel domain which costs too much time.Without decoding,a video synopsis algorithm was proposed for AVS surveillance video in compressed domain.To do so,this algorithm first analyzes the motion vector in AVS bit stream to extract foreground motion macroblocks.Then the valid moving object trajectories are obatained through tracking the foreground macroblocks.At last,the trajectories are recombined with the background frame,which is extracted from the source surveillance video,to gene-rate video synopsis.Comparing with the algorithm in pixel domain,experiments prove that this algorithm achieves similar effect but faster processing speed.
