数字图像的直方图均衡化是常用的图像增强方法，因为均衡化是自动完成的，无需人工干预，而且常常得到比较满意的结果。下面的程序是利用OPENCV提供的函数，实现这个功能。需要OPENCV B4.0的支持，在VC6下编译通过-digital image histogram equalization is used to enhance the image, because equalization is done automatically, the need for manual intervention, and is often quite satisfied with the results. Below is the procedure for the use of OPENCV function, for this function. OPENCV B4.0 need support in that compile under VC6
