Error prediction of imregister results

Is there any function/shared file in Matlab that predict the error on the image registration result obtained with the function imregister?

Try using imabsdiff. However if there are black triangles rotated in, you don't want to compare those so you might have to take the means only in the non-black regions around the edge of the image.

Thank you. However, I have two images that have the same features but the pixel values are different, beacuse they are acquired with two different medical imaging systems. Hence, using imabsdiff is not very useful. I would like to estimate the error associtated to the minimization performed by imregister.
