Description: DCT变换是数字图像处理中重要的变换，很多重要的图像算法、图像应用都是基于DCT变换的，如JPEG图像编码方式。对于大尺寸的二维数值矩阵，倘若采用普通的DCT变换来进行，其所花费的时间将是让人难以忍受甚至无法达到实用。而要克服这一难点，DCT变换的快速算法无非是非常吸引人的-DCT digital image processing is an important transformation, many important images algorithm, imaging applications are based on the DCT, such as JPEG image encoding. For large-size two-dimensional numerical matrix, if only the ordinary for DCT, they spent the time people will be unable to reach intolerable even practical. To overcome this difficulty, DCT fast algorithm is nothing more than a very attractive

Description: 通过阅读这份文档,能够对 JPEG 图形压缩有一定感性的认识, 但其数学原理不需要搞清. 能够通过这, 开始写自己的编码/解码程序. 或者看懂以有的代码. 对有损图形压缩有进一步了解.自己能够改良 JPEG, 比如增加透明色的支持, 加快 JPEG 的解码速度.
-By reading this document to JPEG image compression to a certain emotional understanding, it does not need to understand the mathematical principles. through this, begin to write their own encoding/decoding process. or to read some code. graphics compression harmful to the further understanding. own JPEG can be improved, such as increasing transparency color support and accelerate the speed JPEG decoders.
