The latest High Efficiency Video Coding (HEVC) standard could achieve the highest coding efficiency compared with the existing video coding standards. To improve the coding efficiency of the intra frame, a quad-tree-based variable block size coding structure that is flexible to adapt to various texture characteristics of images and up to 35 intra-prediction modes for each prediction unit (PU) is adopted...
High Efficiency Video Coding (HEVC) achieves the most significant coding efficiency compared with all the existing video coding standards. However, the Intra encoding complexity is increased dramatically since the complex recursive search algorithm for the coding unit (CU) size decisions. In this paper, a fast CU size decision algorithm based on Support Vector Machines (SVM) is proposed to further...

The latest High Efficiency Video Coding (HEVC) standard could achieve the highest coding efficiency compared with all existing video coding standards. However, the computational complexity is increased dramatically because all the possible combinations of the mode candidates are calculated in order to find the optimal rate distortion (RD) cost using Lagrange multiplier. In order to save the coding...
In this paper, we proposed a fast intra mode decision algorithm based on spatial-domain energy for H.264/AVC. First of all, the relevance between macroblock (MB) and its 4x4 sub-blocks is employed in our algorithm to determine the Intra prediction block size. And then, in order to further reduce the computational complexity of Intra mode decision radically, mode candidate reduction algorithm is released...
