Perhaps look at the ratio of the ranges, or the standard deviations, unless you have a specific formula someone recommends.

Like this:
grayImage = 128 * ones(480, 640, 'uint8');
That makes an image with 480 rows and 640 columns with a uniform gray level of 128.

How can I apply it into the output image.I need a output image that is fully uniform gray level,bcz I need a output image with less contrast.
