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 video coding standard High Efficiency Video Coding (HEVC) is developed by Joint Collaborative Team on Video Coding(JCTVC). HEVC can achieve better compression performance than any other coding standards, which adopts the quadtree structured coding tree unit (CTU). In encoding process, the CTU is recursively split into four equally sized coding unit (CU)s. Along with the multiple sizes of...
To improve the coding efficiency of intra frame, a quad tree-based variable block size coding structure which is flexible to adapt to various texture characteristics of images and up to 35 intra prediction modes are adopted in the latest High Efficiency Video Coding (HEVC) standard. To further alleviate the encoder computation load, this paper proposes a fast intra mode decision algorithm based on...
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...
