I have the impression that the center of rotation used for computing the radon transform (skimage.transform.radon) is not correct:
In [8]: tf.radon(z, theta=[0, 90]) Out[8]: array([[ 0., 0.], [ 0., 0.], [ 0., 1.], [ 0., 0.], [ 0., 0.], [ 0., 0.], [ 1., 0.], [ 0., 0.], [ 0., 0.], [ 0., 0.]]) Hrm, you're right; that looks fishy. I wonder if this has to do with the padding that happens beforehand? I don't have access to MATLAB--does their "radon" give similar results? Stéfan
