计算机图形学的直线裁剪程序-computer graphics line cutting procedures

计算机图象处理,图象压缩处理,图像压缩的几个MATLAB算法：分块编码、高斯金字塔、离散余弦变换、单值分解。-computer image processing, image compression, image compression algorithm several MATLAB : Block Coding, Gaussian pyramid, discrete cosine transform, singular value decomposition.

用如求直立主图统计程序。RGB有3个座标，分别是R,G,B，其值从0－255。把0－255分成4段，那么每个座标有4种取值，共可以表示4*4*4＝64种颜色。程序中主要是histogram函数,它有两个参数，第1个参数是一个64位数组，每一位表示一种颜色，其值是该颜色出现的次数。另外两个函数numbercolor是对每个像素计算它的颜色值，fenduan是对参数x返回0－255中的某一段。主函数测试一副图片的颜色直方图的统计。-Used as the main map for vertical statistical procedures. RGB has three coordinates, namely R, G, B, its value from 0-255. The 0-255 is divided into 4, then there are four kinds of each coordinates value, can indicate a total of 4* 4* 4 = 64 kinds of colors. Process is mainly histogram function, it has two parameters, the first a parameter is a 64-digit group, each and every one expressed a different color, its value is the number of the color appears. The other two function numbercolor is calculated for each pixel its color value, fenduan of parameters x the return of a certain period of 0-255. The main function to test a picture of the color histogram statistics.

在对原图像进行双正交7／9三级小波分解后 ，在第二级的水平、垂直、对角以及第三级对角分量上加入水印系数，再经过小波反变换重构出图像。-in the original image Biorthogonal 7/9 3 wavelet decomposition, in the second-class level, vertical, diagonal, and the third-class right angle to add weight coefficient watermark, after wavelet-transform reconstruct images.
