entropy
- The Shannon entropy is a measure of the average information content one is missing when one does not know the value of the random variable. The concept was introduced by Claude E. Shannon in his 1948 paper "A Mathematical Theory of Communication".
DCT
- JPEG标准中规定了4种压缩模式[15]：顺序编码（Sequential encoding），渐进编码（Progressive encoding），等级编码（Hierarchical encoding），无损编码（Lossless encoding）。应用最为广泛的为基于DCT变换的顺序编码，也称之为基准模式(Baseline mode)，其它几种模式都以此为基础。这里，采用了JPEG基准模式对图像进行压缩，在基准模式中，熵编码采用哈夫曼编码方法。 -JPEG standard specif
COLOR-IMAGE-COMPRESSION
- The efficiency of perceptual coding in compressing color images relies on the estimation of perceptual redundancy. In this paper, a color image coder is proposed for perceptually lossless image compression which shapes the coding error as a p

RLC of Binary Image
- 使用游程编码对二值图进行压缩和解压，适合学习，注释详细。 该编码属于无损压缩编码，是栅格数据压缩的重要编码方法。对于二值图有效。(This code belongs to lossless compression coding and is an important coding method for grid data compression. It is valid for the two value graph.)
RLE
- 游程编码，对于二值图像而言是一种编码方法，对连续的黑、白像素数(游程)以不同的码字进行编码。是无损压缩编码的一种。(RLE is a coding method for two valued images, encoding a continuous black and white prime number in different codewords. It is a kind of lossless compression coding.)
