The image registration is done on the basis of rotation, translation and scaling. So the problem is a unconstrained multivariate optimization problem. I wanted to know how to apply the Powell's optimization technique to maximize the mutual information .

Best regards
The optimization of any task presupposes the insertion of the calculation procedure (or image prosecution, that is the same) corresponding in an optimization cycle, for the optimization method that you propose or for any other.
