Abstract

The goal of this work is to find a fast method for motion estimation and motion segmentation using proposed model. Recent day Communication between ends is facilitated by the development in the area of wired and wireless networks. Block matching algorithms are very useful in achieving the efficient and acceptable compression. Block matching algorithm defines the total computation cost and effective bit budget. Recently fast search algorithm for video coding using Orthogonal Logarithmic Search Algorithm (OSA) has been proposed. Motion estimation is the most time consuming operation in a typical video encoder. This paper presents a novel method using three step algorithm with modified search pattern based on dead cell for the block based motion estimation. It has been found that from the original Three step Search (3SS/TSS ) method, the PSNR value has increased and the computations and thus computation time (faster) has been reduced significantly .The experimental results based on the number of video sequences were presented to demonstrate the advantages of proposed motion estimation technique.
