A Fast CU Division Algorithm for Intra Prediction in HEVC
High Efficiency Video Coding (HEVC) is a new video coding standard following H.264/AVC. By introducing a flexible coding unit (CU), which can be recursively divided from 64 64 to 8 8 blocks in a Quadtree-Structure, HEVC achieves significantly higher coding efficiency than the previous standards. With the flexible CU structure, HEVC can effectively adapt to complicated contents with a smaller...

High Efficiency Video Coding is a new video coding standard after H.264/AVC. By introducing a flexible coding unit, which can be recursively divided from 64×64 to 8×8 blocks in a Quadtree-Structure, HEVC achieves significantly higher coding efficiency than the previous standards. With the flexible CU structure, HEVC can effectively adapt to highly varying contents with a smaller CU or to flat c...
متن کاملFast and adaptive mode decision and CU partition early termination algorithm for intra-prediction in HEVC
High Efficiency Video Coding (HEVC or H.265), the latest international video coding standard, displays a 50% bit rate reduction with nearly equal quality and dramatically higher coding complexity compared with H.264. Unlike other fast algorithms, we first propose an algorithm that combines the CU coding bits with the reduction of unnecessary intra-prediction modes to decrease computational comp...
متن کاملFast Intra Prediction Mode Decision Algorithm for HEVC
This paper proposes a novel fast intra-prediction algorithm that exploits the Sobel operator to replace the Hadamard transform used in the Rough Mode Decision (RMD) process of intra prediction in High Efficiency Video Coding (HEVC). First, the Sobel operator is used to calculate the vector direction of each pixel. A judgment is then made on which prediction mode the vector belongs to, and a his...
متن کاملThe Algorithm of Fast Intra Angular Mode Selection for HEVC
In this paper, we propose an algorithm of angular mode selection for high-performance HEVC intra prediction. HEVC intra prediction is used to remove the spatial redundancy. Intra prediction has a total of 35 modes and block size of 64x64 to 4x4. Intra prediction has a high amount of calculation and operational time due to performing all 35 modes for each block size for the best cost. The angula...
