I need some algorithm for distortion processing

My problem is: I have a set of 4 points O, A, B, C locating on a surface. Due to distortion of that surface, the points A, B, C are moved to new positions which are A', B', C'. Now I want to find new position of O that satisfies root mean square error (RMSE) of two sets of distances (O'A', O'B', O'C', O'O) and (OA, OB, OC, OO) is minimal. Dose anyone know which algorithm can solve my problem? Thank you!

That's not distortion in the true optical sense. Distortion is where the distance the point moves is proportional to the cube of the distance from the optic axis, and it's radial, which is quite unlike what you have. You have some arbitrary warping of the image. Try imwarp() or related functions.

Well obviously if the new position O' is the same as O, that would give the least possible RMSE you could get.
