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.

source and destination color spaces, S = dest<-src , or
alternatively, S = src->dest . Supported color spaces are

Description: 压缩包的内容包括:1.有关JPEG和DPCM算法的文章;2.实现其算法的压缩程序3.有关图像压缩方面的资料。读者请注意:
<1>这里讨论的是灰度图像的压缩不涉及彩色图像。
<2>实现压缩时,输入的图像数据采用一种自定义的格式(com 格式),前四个字节记录图像的宽度和高度,之后就是逐
行的图像数据,图像的开头和结尾没有任何标记。这种格式的图像数据是从BMP图像中得到的。
<3>这里没有JPEG算法的解压程序,压缩后的数据存成标准的JPEG文件格式,任何视图软件都可以打开。DPCM方法中的解
压缩程序将数据仍然存成com格式,可以将其转成PGM格式观看,压缩包中由com转为PGM格式的程序。
<4>所有的C程序均是在Linux(Rethat7.3)下完成。-Compressed package includes: 1. The JPEG and DPCM algorithm article 2. To achieve its compression algorithm procedure 3. The image compression information. Readers please note:
<1> discussed here is the gray image compression does not involve color images.
<2> to achieve compression, the input image data using a custom format (com format), record the first four bytes of the image width and height, and then is gradually
Line of image data, image mark the beginning and no end. This format of image data is obtained from the BMP image.
<3> There are no procedures for JPEG decompression algorithm, compressed data stored as a standard JPEG file format, you can open in any view. DPCM method of solution
Compressed program data is still stored as com format, you can watch it turn into a PGM format, compressed in the com format to PGM program.
<4> All the C programs are in Linux (Rethat7.3) to complete. Platform: |
