Non rigid Image Registration

Is there any specific way to perform feature based non-rigid registration in gray-scale images? i have been using matched points between the two images but it doesn't seem to work . ANY idea on how to move forward with the task is very welcome. Thank you.

Try imwarp()

thank you for the answer,i was looking for finding an inverse mapping between the two images using the matched points. can you please give me any idea on a more theoretical basis? your kindness very much appreciated.

That's a lot more complicated - to start with two sets of points and figure out what possible mathematical formula(s) could map them there. I have no idea.

It looks like point_registration.m in this FEX package does this sort of thing.

Take a look at imregdemons in the image processing toolbox.
