HEVC Information-Hiding Algorithm Based on Intra-Prediction and Matrix Coding

An Information Hiding Algorithm for HEVC Based on Angle Differences of Intra Prediction Mode

An information hiding algorithm for HEVC is proposed. For 33 kinds of directional prediction modes in the encoding process of 4×4 luminance blocks, intra prediction modes are mapped to the angle values. We are establishing a mapping relationship table between the angle differences and secret information. Modifying the intra prediction modes to embed secret information is based on the mapping. T...

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 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...
