• A fast-motion-estimation (ME) algorithm called a "breakirig-off-search (BOS)" was developed. It can improve processing speed of the full-search (FS) method by a factor of 3.4. The BOS algorithm can not only sometimes achieve better visual quality than FS, but can also solve visual degradation problems associated with conventional fast-ME algorithms whenever picture patterns change (I.e., presence of scene changes). The power dissipation of a 0.6-μ CMOS parallel Wallace-tree motion estimator using BOS was reduced to about 281 mW which was 1/28.7 that of the 0.6-μm CMOS binary-tree motion estimator using FS.
