<div dir="ltr"><span style="font-family:arial,sans-serif;font-size:13px">Hi,</span><div style="font-family:arial,sans-serif;font-size:13px"><br></div><div style="font-family:arial,sans-serif;font-size:13px">I'm combining two affine transformations computing a velocity field sum. Then, I'm using the ExponentialDisplacementFieldImageFilter to compute a diffeomorphic displacement field. Since this method is diffeomorphic, the inverse transformation should be always available. So I'm computing the displacement field and it's inverse (I use the ExponentialDisplacementFieldImageFilter with ComputeInverse). The problem is, when I use this strategy with two rotations (two concentric circles) in opposite directions, applying the inverse displacement field is not giving the initial position(so, the diffeomorphic transformation is not verified). Do you have any information about some problem in this class? </div>
