Abstract
Image rototranslations can be estimated in the frequency domain by exploiting the fact that a rotation of the space domain maps itself into a rotation of the frequency domain. It is shown that a distortion enjoys such a property if and only if it is an affine transform. Proofs for this theory are presented.File in questo prodotto:
