Abstract

Classical block-based motion-compensated video coders need to nd and code a motion eld with one motion vector per image block. All motion vectors are computed and encoded with the same xed accuracy, typically 1 or 1/2 pixel accuracy. Higher motion vector accuracies have been shown to signiicantly reduce the total bit rate in some video sequences, but motion… (More)
