I need to compute six correlation coefficients (red-green, green-blue, blue-red, red-grey, green-grey, and blue-grey) for both the whole sub-image and the lesion area respectively,one example shall do it for the 6 as of the same logic shall be applied,as well as calculating the Energy based on color extraction not texture or regionprops one(R,G,B,Gray) but one color space example shall do.. thanks

Did you try corr()?
coeff = corr(redChannel(:), greenChannel(:));

Use histogram() or histcounts() to get "Prob" in the first formula.
For the second formula, I have no idea whatsoever what "details" is.
