N2 - The High Efficiency Video Coding (HEVC) standard can achieve approximately 50% bit-rate reduction that compares with H.264. To enhance intra coding efficiency in HEVC, an increase in the number of intra modes from 9 to 35 is adopted. However, this technique drastically increases computational complexity of intra mode selection. In this paper, we propose two novel techniques to reduce the number of candidate intra modes. One is block texture detection and the other is Sum of absolute transformed differences (SATD) classification. The results indicate that the proposed method can reduce the encoding time by approximately 44% on average under all intra configurations.
