DCT Based Fast INTRA Mode Decision Method for HEVC Coding

High Efficiency Video Coding (HEVC) can significantly improve coding efficiency by using 35 intra prediction modes, which lead to a substantial increase in coding complexity yet. In this paper, a fast intra mode decision method for HEVC based on DCT is proposed. The algorithm estimates the texture direction of the prediction block (PB) by using discrete cosine transform and reduces the number o...

Fast Coding Unit Decision Algorithm for HEVC Intra Coding

—High Efficiency Video Coding (HEVC) exploits quad-tree structured Coding Unit (CU) to improve compression efficiency. It saves about 50% coding bits as compared with the former standard H.264/AVC high profile. However, the computational complexity is dramatically increased for more partition blocks and coding modes supported in HEVC. In this paper, a fast CU decision algorithm is proposed to ...

A Fast Block Size Decision For Intra Coding in HEVC Standard

Intra coding in High efficiency video coding (HEVC) can significantly improve the compression efficiency using 35 intra-prediction modes for 2N×2N (N is an integer number ranging from six to two) luma blocks. To find the luma block with the minimum rate-distortion, it must perform 11932 different rate-distortion cost calculations. Although this approach improves coding efficiency compared to th...
