I want to calculate the correlation coefficient for my image pixel(binary)and after that for my encrypted image. I know corr2 is for calculating the correlation coefficient for two images.
But is there a function for calculating the correlation coefficient for one image in matlab?Actually I want a number not a matrix

Hello, I am pretty sure corr2 returns a value , http://www.mathworks.com.au/help/images/ref/corr2.html
You need to compare with something to get a correlation coefficient, either with other images or other parts of your image
