1. A computer-implemented method, comprising: identifying a first image patch and a second image patch, the first image patch corresponding to a first set of spatial frequency signals, and the second image patch corresponding to a second set of spatial frequency signals; determining a reference frequency ({tilde over (ω)}) based on the first set of spatial frequency signals and the second set of spatial frequency signals; equalizing the first image patch and the second image patch based on the reference frequency by scaling the first image patch and the second image patch by π/{tilde over (ω)} to spread the frequencies over a domain; and determining correspondence matching between the equalized first image patch and the equalized second image patch.
