本程序是用matlab写的，实现对图像进行二维预测与Lloyd-Max量化压缩。是有损压缩。附有程序所用的图片。-The program is written in matlab to achieve two-dimensional projections of images and Lloyd-Max Quantization. Is a lossy compression. With a program with pictures.

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
