I've never heard of that. Are you sure you're not talking about the "gray level co-occurrence matrix" performed by graycomatrix() in the Image Processing Toolbox?

it is a simple matrix solution...but works for only certain value

I thought you said "I AM NOT FINING THEORY OR MATERIAL" meaning that you didn't know any article that described the algorithm. But it sounds like now, that you do (you gave the citation) - and you say it is simple. So, can you program it up in MATLAB?

yes i found the required material now...will soon come up with code

Hello, Do you mean for a image M*N you would like to create a matrix M*N *M*N such that the elements are values of the gray difference?
