Fast Intra Prediction Algorithm with Transform Domain Edge Detection For HEVC

Abstract

To solve the high computational demand of intra prediction in the latest HEVC (High Efficiency Video Coding) standard, this paper proposes a fast intra prediction algorithm with three step mode selection and the transform domain edge detection. The simulation results show that the proposed algorithm can save 44.2% encoding time in average for all-intra High Efficiency case compared to the default encoding scheme in HM-6.0rc1, with slightly 2.8% BD-rate increases.
