Sheno39, could you please elaborate? How do you define your neighborhood? (4 connected, 8 connected or something else?) Do you need the relative position of the max for each pixel or the absolute location in the image?

Jan already asked that in the duplicate (prior) question: http://www.mathworks.com/matlabcentral/answers/89643-how-to-find-the-original-index-of-stored-elements-in-an-array-of-an-image I'd also like to know what is to be done with that information, to see if it's really needed or not. For example if they're using dynamic programming checkerboard method to solve a shortest path problem or something like that where the direction from a pixel is needed.
