Hello there,

I made a mesh and I picked up the contours of this mesh as some points and I have an MRI image. So I want to move these points based on a heart on this mri image. I have tried to read like a lot of articles on morphing, points wrapping and so on.... but they are explaining either morphing between two image or two mesh. So I am a kind of stocked.

I appreciate any idea! Sareh

Try maketform() and tformfwd(). Or else imtransform. You pass the actual point locations and the desired locations into maketform() and it gives you a transform. Then use tformfwd() to apply this transform to warp your "bad" image into your "desired" image.

ALso, see Steve's blog: http://blogs.mathworks.com/steve/2006/08/04/spatial-transformations-defining-and-applying-custom-transforms/
