Abstract

H.264 video coding standard introduces motion estimation with multiple block sizes to achieve a considerably higher coding efficiency than other video coding algorithms. However, this comes at the greatly increased computing complexity at the encoder. In this paper, a method is proposed to eliminate some redundant coding modes that contribute very little coding gain. The simulation results show that the algorithm can remarkably decrease the complexity at the encoder while keeping satisfying coding efficiency.
