How to generate a transformation matrix from the displacement fields using imregdemons

I've registered a moving image to a fixed using imregdemons:

[D,moving_reg] = imregdemons(moving,fixed)

...and I'm looking for a way to compute or output the transformation matrix for said image using the displacement fields D.

Any ideas? Thanks!

Currently there is no way to directly get the transformation matrix from the displacement field.

Instead, you can use imregtform to find the transformation matrix.

For more information on how to use it, youcan refer to the following link:

Hope this helps!
