Abstract
The paper proposes three modifications to the 3-step hierarchical search block-matching algorithm for video coding: a multiple-winner search that improves the estimation accuracy, a method of subsampling that reduces computation and input data amount, and an overlapping strategy that improves the accuracy of large-area search. Experimental results show that combining these techniques provides high-speed and high-precision motion estimators with reduced on-chip buffers and lowered input bandwidth requirements. © 1994 IEEE.
