A simple and efficient search algorithm for block-matching motion estimation 论文

摘要

The three-step search (TSS) algorithm for block-matching motion estimation, due to its simplicity, significant computational reduction, and good performance, has been widely used in real-time video applications. A new search algorithm is proposed for further reduction of computational complexity for motion estimation. It is shown that the proposed algorithm is simple and efficient and requires about one half of the computation for the TSS while keeping the same regularity and good performance.
