How to change the greyscale intensities to the prescribled mean and standard deviation?
Hello all,
Hope this would be the stupidest question you have ever read. I am very new in image processing. Now I have many 8-bit greyscale images, and I want to set the mean and standard deviation to 0.25 for further processing linearly. Could anyone tell me how to do that? Thanks in advance.
