Abstract
An efficient intra mode selection algorithm is proposed to reduce the computational complexity of inter frames for the H.264|AVC video encoding system. We propose an adaptive thresholding algorithm based on distribution characteristics of the sum of the absolute differences (SAD) of the best inter mode. Through comparative analysis, the proposed algorithm shows better speed up ratio with a negligible quality loss.
