在DSP上市现了灰度均衡，灰度均衡是把图像中像素值在灰度级上重新分配的一个过程，使输入图像转换为在每一个灰度级上都有相同的像素点的输出图像。-In the DSP market is the gray balance, gray balance is to the image pixel gray level values in the re-allocation of a process to convert the input image gray level in each pixel h

按照C语言程序实现对128x128像素点、256灰度等级灰度图像的灰度直方图显示-In accordance with the C language program to 128x128 pixels, 256 gray scale histogram display grayscale images
