Abstract
In Wyner-Ziv video coding (WZVC), the majority of the computational complexity has been shifted from encoder to the decoder in comparison to its conventional video coding technologies. This paper presents a low-complexity frame/block motion activity classification algorithm for WZVC. Improved rate-distortion performance is achieved by adjusting the coding mode of key frame according to the motion activity along the sequence. Simulation results of proposed technique show a consistent improvement in coding efficiency in comparison to the state-of-the-art TDWZ codec.
