Abstract
The new generation video compression standard of high efficiency video coding (HEVC) improves compression performance by 50% compared with the previous video coding standard, while also increases the coding complexity greatly. In order to reduce the complexity and further improve system efficiency, a fast intra prediction algorithm with simplified prediction modes is proposed. Based on the correlation between rough mode decision (RMD) and the best prediction mode in the intra prediction mode selection, and the utilization rates of 35 intra prediction modes, the proposed algorithm removes some prediction modes in the candidate list and reduces the computation time of the rate distortion (RD) cost. Experimental results show that compared with HEVC intra prediction coding algorithm, the proposed fast intra prediction algorithm increases efficiency by about 20% with no significant changes for compression bit rates.
