Zl. He et Ml. Liou, DESIGN OF FAST MOTION ESTIMATION ALGORITHM-BASED ON HARDWARE CONSIDERATION, IEEE transactions on circuits and systems for video technology, 7(5), 1997, pp. 819-823
Most fast block-matching motion estimation (BMME) algorithms are desig
ned to minimize the search positions (or checking points) in a given s
earch range in order to speed up the computation, In this paper, we in
troduce a fast BMME algorithm based on the consideration of hardware i
mplementation, We use a one-dimensional (1-D) systolic array as the ba
sic computing engine, In order to utilize this engine efficiently, we
process several adjacent checking points, called checking vector, simu
ltaneously, We propose a checking-vector-based search strategy and sho
w that it can achieve a better algorithmic performance and can be very
cost-effective in terms of hardware implementation for low bit-rate v
ideo applications.
