Abstract :
The H.264/MPEG-4 AVC is the video coding standard which achieves much higher coding efficiency than previous standards such as H.263 or MPEG4. However, this performance gain comes at the cost of a greatly increased computational complexity. In this paper, a very fast mode decision algorithm is proposed for H.264 video coding, which can enables the H.264 encoder to be effectively adopted for video communications and mobile implementations. Simulation results show that the proposed algorithm can efficiently reduce the computational cost up to 90% with similar visual quality and bit rate
