In this paper we propose an efficient fast block-matching algorithm for motion estimation. Two different patterns, 3×3 and 5×5 cross patterns alternative in inner ring, and three search strategies, including prediction, threshold, and hierarchy, are utilized to form the procedure of the proposed algorithm. The simulation results show that number of search(More)
An intrinsic property, wherein the set of numbers formed using the magnitudes of a basis vector's elemen& is the same for all basis vectors in a length-2" type411 discrete sine transform (DST) and discrete cosine transform (DCT), is proved in this paper. We also show that the set of numbers formed using the magnitudes of any basis vector's elements in a(More)
