摘要：
A new fast intra-prediction algorithm for HEVC is proposed in this paper. The algorithm makes full use of spatial correlations among video sequences, decides the best size of CU by referring neighboring coded CUs' size and the best prediction mode of PU by referring the up layer PU modes. The experimental results show that the algorithm averagely achieves 45.2% reduction of intra coding time compared to the default encoding scheme in HM2.0 with drops of 0.05dB PSNR and increases of 0.10% bits rate.
