映像切替方法が符号化処理に与える一考察 －動きベクトル検出の精度向上－

In the video encoding process which is necessary for the transmission of video signal, it is common that the image deterioration is caused when the image switching. This is recognized that lowering of similarity to previous frame is primary factor. To improve that similarity, this paper describes the measures of sharp change detection of video signal.
