Abstract

Motion estimation plays an important role in real-time video coding because it can improve compression efficiency greatly. Block matching algorithms are popular in motion estimation. The full search algorithm is the most obvious and simplistic block matching algorithm, but its high computational cost limits its practical use. Many fast algorithms are constantly proposed. Fast algorithms can greatly reduce the computation by only searching selected positions in the search window. In this paper, several block matching algorithms (including FS, TSS, TDL, and CS) are introduced and compared by compute simulation. Experiment results show that the full search algorithm provides high compression with low distortion, but it costs much time; fast algorithms reduce the computational time significantly while suffer performance loss; the three-step search algorithm is the most practicably algorithm in the fast algorithms.
