摘要

A typical H.264 video encoder (such as JM) selects the best motion vector based on the sum of absolute difference (SAD) and the sum of absolute transformed difference (SATD) in different accuracy layers. In this paper, we propose a jointly optimal approach that selects the best motion vector that mi-nimizes the rate-distortion cost of the quantized transform coefficients. We test the proposed scheme on a number of sequences. The results indicate that our scheme provides a bit-rate gain up to 4% for P pictures.
