New Fast Search Block Matching Motion Estimation Algorithm for H.264 /AVC

Abstract

Video encoding algorithms with less complexity are required in many real time video coding applications. Motion Estimation (ME) is computationally intensive part of video compression. This paper introduces One bit transformation ME algorithm, which transforms the video sequences from multi-bit to a single bit per pixel representation and then used conventional motion estimation search strategies, this will reduce the arithmetic calculations and hardware complexity while maintaining almost good compression performance. In this paper, we propose an efficient fast search ME method for one bit transform to reduce computations involved in determining motion of blocks in a frame. The proposed Fast search algorithm effectively estimates the motion information in video. Experimental results shows 50% reduction in computations with a marginal loss of 3% PSNR compared to the conventional Exhaustive search algorithm.
