what are the formulae for entropy and energy. and how to find them for a given 2D image using MATLAB??

Stalin answered this in your duplicate question by giving you a link to my answer to another poster.

In short, you can get the energy in uncalibrated units by summing the image, and you can get the entropy by using the entropy() function.

yes but sum(I) is returning a large array of values. i want to calculate the energy of the image as a whole. [ 'I' is the grayscale image used]
