这个算术编码是对大量英文文本进行压缩，只适合英文文本压缩（适当修改可以用于图像压缩）-The arithmetic coding is a lot of English text compression, is only suitable for English text compression (with appropriate modifications can be used for image compression)

算术编码是图像压缩的主要算法之一。　在给定符号集和符号概率的情况下，算术编码可以给出接近最优的编码结果。使用算术编码的压缩算法通常先要对输入符号的概率进行估计，然后再编码。这个估计越准，编码结果就越接近最优的结果-Arithmetic coding algorithm was a major one compressed image. In a given symbol set and symbol probability case, arithmetic coding can give nea

图像处理,这个是关于求图像的信息熵，算术变换，图像压缩等等(Image processing, this is about finding the entropy of the image, arithmetic transformation, image compression and so on)
