I am using imregtform to get the transformation matrix and register images, Affine and Rigid to compare them. After that I want to extract translation, rotation, scale etc from the transformation matrix. I know how to do that from a homogenous matrix but the method returns an affine3d 4x4 matrix that is not homogenous.
Could you please tell me how to convert it? This is how it looks:
