摘要

In this paper, an efficient cost function for mode decision in H.264/AVC is proposed. The proposed cost function is based on integer transform coefficients, where the rate and the distortion are jointly modeled by the number of nonzero quantized coefficients, the sum of absolute integer transformed differences (SAITD) and sum of squared integer transformed differences (SSITD). Comparing to the high-complexity cost function, which should be calculated from real bit-consumption and true reconstructed distortion for each coding mode, the proposed efficient cost function can achieve 79.93% and 22.61% time savings of computing rate-distortion cost and overall encoding, respectively, while introducing only slight degradation with 1.05% bit-rate increment and 0.049dB PSNR drop.
