How are you measuring it? Why not search the File Exchange for contrast: https://www.mathworks.com/matlabcentral/fileexchange/?utf8=%E2%9C%93&term=contrast
or check some of the links on the right side of this page?

I have a image that contains a tumor and I want to calculate the contrast ratio for this tumor. Is this method correct? Thank you
I found this example but I don't need you.
