An Improved Three-Step Search Algorithm with Zero Detection and Vector Filter for Motion Estimation

Abstract

In this paper, a new fast block matching algorithm is developed for motion estimation. The motion estimation algorithm use improved 3-step block matching (ITSS) algorithm that can produces better quality performance and less computational time compared with three-step search (TSS) algorithm and correct the motion vector by using Zero Detection and vector filter. From the experimental results, the proposed algorithm is superior to TSS in both quality performance and computational complexity.
