Reusing Search Window Data and Exploiting Early Termination in Variable Block Size Motion Estimation Park, Taewook; Hur, Ahrum; Lee, Seongsoo;
In HEVC, motion estimation is performed independently for each variable block size. So it requires several times of search window data, and also it is difficult to exploit early termination. In this paper, a new method is proposed to exploit search window data and early termination in variable block size. When applied to TZS algorithm, it reduces pixel comparison and search window data accesses to 1/3.7 ~ 1/2.9 with negligible image quality degradation.
