Abstract
To reduce an amount of computation of full search algorithm for fast motion estimation, we propose a new and fast matching algorithm without any degra dation of predicted images. The computational reduction without any degrada tion comes from adaptive matching scan algorithm according to the image com plexity of the reference block in current frame. Experimentally, ae signifi cantly reduce the computational load compared with conventional full search algorithm.
