基于图像直方图均衡化的公式来编程。像素一共分为256个灰度阶，每个灰度阶用数组的一个相应nk[？]来储存它的个数，然后计算tk[？]。-Based on image histogram equalization formula programming. Pixel is divided into a total of 256 gray-scale bands, each of the gray band with a corresponding array nk [? ] To store th

学习计算机图形学的同学有福了，这是图像颜色量化程序，将256灰度变为2阶，4阶，8阶-Computer graphics, image color quantization
