Comparison of Subpixel Phase Correlation Methods for Image Registration

Abstract

The popular phase correlation method (PCM) for image registration has been extended to subpixel accuracy by several alternative algorithms, each claiming accuracies on the order of 0.02 - 0.03 pixels for 256 x 256 images. However, the performance reported in the literature is sometimes based upon idealized images or upon just a few selected images. This leaves users in doubt as to which algorithm is truly superior. This work compares three subpixel PCM algorithms using a common test set of realistic images derived from satellite imagery. Of the three algorithms investigated in this work, the one of Guizar et al. (conceptually the simplest) consistently performed best.
