Multi-Level, Multi-Step Motion Estimation Algorithm

摘要

In this paper, we propose a multi-level block matching algorithm using motion information in blocks. In the proposed algorithm the block-level is decided by the motion de- gree in the block before motion searching procedure, and then adequate motion searching performs according to the block-level. Which improves computational efficiency by eliminating an un- necessary searching process in no motion or low motion regions, and brings more accurate estimation results by deepening motion searching process in high motion regions.
