Abstract :
Fast as well as precise multiresolution motion estimation (MRME) is described. We propose a two-step block matching with different block sizes at the approximation band to estimate precise block motion in the MRME technique. Experimental results show that the proposed method gives better performance when compared with the conventional MRME method in terms of PSNR and processing time to estimate the motion
