Title: | Modifications and performance improvements of 3-step search block-matching algorithm for video coding | Authors: | Jong, Her-Ming LIANG-GEE CHEN TZI-DAR CHIUEH |
Issue Date: | Apr-1994 | Start page/Pages: | 256 - 259 | Source: | ISSIPNN 1994 - 1994 International Symposium on Speech, Image Processing and Neural Networks, Proceedings | Conference: | 1994 International Symposium on Speech, Image Processing and Neural Networks, ISSIPNN 1994 | 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. |
