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。-Since the rate allocation algorithm is not defined by the standard, JJ2000 has implemented the so-called EBCOT algorithm.
Information about this algorithm can be found in the Verification Model (see [3]). The choice of using this algorithm makes
it possible to run extensive tests and code-streams exchange with the Verification Model software and thus ensure verification
of the texts and descriptions of the standard.
