图像jpeg压缩算法介绍及其源码

上传者: hillwing0819 | 上传时间: 2019-12-30 03:04:32 | 文件大小: 279KB | 文件类型: rar
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: 这里讨论的是灰度图像的压缩不涉及彩色图像。 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。 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。 所有的C程序均是在Linux(Rethat7.3)下完成。
