Abstract: Motion estimation is one of the most important parts in the digital video encoding progress, and it is effective to have a motion estimation algorithm with low computation and complexity. This paper proposes a modified Bit Plane Matching(BPM) algorithm by choosing the threshold value and the candidate motion vector, which can reduce the computation and complexity of the motion estimation progress and have an image improvement for the sequences.

Key words: motion estimation, Full Search(FS) algorithm, fast search algorithm, Bit Plane(BP), Bit Plane Matching(BPM) algorithm
