Description: (1)将整幅图像分成4×4块，计算每一块中所有象素RGB三个颜色通道的颜色平均值，并以此作为该块的代表颜色（主颜色）。
(2)将各块的颜色平均值进行离散余弦变换（DCT），得到DCT系数矩阵。DCT是一种分离的变换，是国际静止图像压缩标准JPEG的基础。由于大多数图像的高频分量较小，相应于图像高频分量的系数经常为零，加上人眼对高频成分的失真不太敏感，所以可用更粗的量化。因此，在一般检索中可以利用部分DCT系数作为特征向量。
(3)对DCT系数矩阵进行之字形扫描和量化，得到DCT系数。
(4)对于R、G、B三个通道，分别从DCT系数中取出4个低频分量，形成12个参数，共同构成该图像的颜色特征向量。-err

Description: Convert a color image between color representations.
B = COLORSPACE(S,A) converts the color representation of image A
where S is a string specifying the conversion. S tells the
source and destination color spaces, S = dest<-src , or
alternatively, S = src->dest . Supported color spaces are
RGB R G B Red Green Blue (ITU-R BT.709 gamma-corrected)
YPbPr Luma (ITU-R BT.601) + Chroma
YCbCr / YCC Luma + Chroma ("digitized" version of Y PbPr)

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.
