Abstract
Relaying on a temporal correlation among successive pictures and using a hierarchical recursive motion estimation algorithm, the hardware complexity of video coders complying with the MPEG-2 standard can be significantly reduced without an appreciable loss of quality of the video images being transferred. Relaying on a temporal correlation among successive pictures is also performed on a spatial correlation of motion vectors of macroblocks of the currently processed picture.
