An Improved Decoder Motion Estimation Algorithm in Distributed Video Coding
Cunying Chen, Hua Zhang · 2016
This paper focuses on the theory of side information generation, and puts forward an improved scheme based on unsupervised learning of motion vector which improves system's performance.The scheme generates and optimizes side information through the introduction of rate control at the encoder and EM model at the decoder.Lastly, a DVC system is implemented based on the scheme, its principle of work is presented.A MATLAB simulation system has been developed for the DVC system.By comparing with typical side information generation methods, the outstanding performance of the proposed side information generation scheme is justified, and the validity and advantages and feasibility of the proposed DVC system are demonstrated.
