Description: 图像压缩主要目的是为了节省存储空间，增加传输速度。图像压缩的理想标准是信息丢失最少，压缩比例最大。不损失图像质量的压缩称为无损压缩，无损压缩不可能达到很高的压缩比；损失图像质量的压缩称为有损压缩，高的压缩比是以牺牲图像质量为代价的。压缩的实现方法是对图像重新进行编码，希望用更少的数据表示图像。-The main purpose of image compression to save storage space, increase the transmission speed. The ideal image compression standard is a minimum loss of information, the maximum compression ratio. Compression without loss of image quality is called lossless compression, lossless compression can not achieve high compression ratio loss of image quality and compression is called lossy compression, high compression ratio at the expense of image quality for the price. Compression of the image is re-encoded data that wish to use fewer images. Platform: |

Description: 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 used are typically for lossy compression applications. CABAC is notable for providing much better compression than most other entropy encoding algorithms used in video encoding, and it is one of the key elements that provides the H.264/AVC encoding scheme with better compression capability than its predecessors.
