基于dct变换的水印算法，并进行有损压缩情形下的水印嵌入和提取-Dct transform based watermarking algorithm, and for lossy compression case the watermark embedding and extracting

Context-adaptive binary arithmetic coding (CABAC) is a form of entropy encoding used in the H.264/MPEG-4 AVC and High Efficiency Video Coding (HEVC) standards. It is a lossless compression technique, although the video coding standards in which it is
