An extension of the Multiresolution Fourier Transform (MFT) is presented and shown to have a predictable redistribution of energy as a result of affine transformations of the input signal. An approximation based on the discrete MFT then forms the basis of a computationally efficient algorithm for estimating local affine coordinate transformations between pairs of image regions. Results of applying the technique to an image registration problem illustrate its potential. }, abstract-url={http://www.cs.bris.ac.uk/Publications/pub_master.jsp?id=1000136}, url={http://www.cs.bris.ac.uk/Publications/Papers/1000136.pdf}, keyword={Computer Vision}, pubtype={102} }
