摘要

An effective and efficient method is proposed for motion estimation in a video sequences. The paper outlines a search technique based on the traditional once-at-a-time search (OTS) and propose a fast predictive version called modified once-at-a-time search (MOTS) algorithms. The modification is based on utilizing the existing inter-block correlation between the motion vectors of the adjacent blocks. The performance of the enhanced modified technique is compared with the modified one in terms of objective quality measurement (PSNR) and searching time. Test results indicate that the performance of the inter frame coding based on using modified block matching algorithm in addition to encoding the error of the highly distorted blocks is better than the results of modified OTS. The results show encouraging reduction of prediction.
