An Adaptive Motion Estimation Algorithm Based On Conjugate Gradient

Motion estimation is rather complex in computation and spends much time in the interframe video compression. Fast motion estimation has always been a favorite to the researchers in the field. For improving the speed of the searching, a new adaptive fast algorithm is proposed with conjugate gradient in this paper. Then it is composed of the inspection of the brim and the prediction of initial search point. Experiments show that the algorithm could obtain very good search result at very low computation cost
