I want to compare different images to get the image with the best contrast. I know about the Weber contrast, but I need a normalized contrast value (in the range between 0-1 or other). Is there a simple method to do this in openCV?

    Also compare the cdfs of two images. First one has a steep slope, while second one is almost a straight line showing all pixels are equi-probable. Another important feature is that, even if the image was a darker image (instead of a brighter one we used), after equalization we will get almost the same image as we got.
