Aiming at the problem that data hiding algorithm of high efficiency video coding (HEVC) has great influence on bit rate and visual quality, an information based intra prediction mode matrix is proposed. Firstly, 8 modes are selected from 4×4 luminance blocks in I frame to embed hidden information. Then, Least Significant Bit (LSB) used modulate LSB last mode. Finally, modulated block re-encoded...

Prediction in HEVC exploits the redundant information fame to improve compression efficiency. The computational complexity of prediction is comparatively high as it recursively calculates depth by comparing rate-distortion optimization cost (RDO) exhaustively. deep learning technology has shown a good mark this area compared traditional signal processing because its content-based analysis and a...
