Abstract

An image registration algorithm based on combining phase differences at uniformly distributed spatial frequencies is described. The scheme accomodates 2-d disparities and when incorporated within a coarse-to-fine analysis over scale, allows for fast registration even in the presence of large disparities. Experiments performed on random noise stereo pairs demonstrate the potential of the approach.
