Novel intra prediction algorithm using residual prediction for low power multimedia codecs

This paper proposes a novel residual prediction algorithm to improve the coding efficiency. It extends the scope of prediction to the residual data. The proposed algorithm is adopted for intra prediction which accounts for a major portion of the bit stream. The simulation results show that the proposed algorithm can reduce the bit-rate by up to 4.34% compared with the JM reference software without any degradation of the peak signal to noise ratio. By incorporating basic hybrid video coding techniques into the encoder, the proposed residual prediction algorithm can significantly improve the coding efficiency.
