A simple recursive motion estimation technique for compression of HDTV signals

Considers motion-compensated DCT coding of HDTV signals for digital home-use HDTV recording. In the video encoder, motion estimation is required for enhanced prediction of video frames in the temporal direction. In order to reduce the number of motion vectors applied in the motion estimation, the author presents a class of block-based recursive motion estimators, using 15-20 different motion vectors only for deriving a reliable motion estimate which can compete with full-search motion estimation techniques
