Title: A New Fast Motion Estimation Algorithm Based on Video Sequences Characteristics
Abstract: Motion estimation algorithm,as one of the significant issues to video compression encoding,is studied in this paper.A new fast motion estimation algorithm is advanced.The correlation of video macro block is used to predict start point of searching.The searching mode is designed according to the center-biased characteristic of motion vector of video sequences and the directionality of the SAD distribution.The algorithm avoids and reduces unnecessary searching,making motion estimation faster and more accurate.This algorithm keeps the image quality as well as reduces the computations complexity.
