Hello, I need to find the radial intensity difference for different radii intervals. Is there any suitable function in opencv which helps to find it? Thanks.

Afaik, there doesn't exist a direct function for that but you can create circular masks with circle() (see http://docs.opencv.org/modules/core/doc/drawing_functions.html?highlight=circle#circle), mask your data with it and compute the gradients on your own.
