Claim One:
1. A computer-implemented method for determining a pixel shift between an image pair captured by image sensors, the method comprising: accessing a first image and a second image of the image pair captured at a substantially same time, the images comprising image data representative of an overlapping field of view between the image sensors; determining edge magnitude and edge phase of the image data corresponding to the first image and the second image based on a luma component of the image data; determining an edge length for each of a plurality of candidate edges identified based at least in part on the determined edge magnitude and edge phase of the image data; identifying, by one or more processors, one or more edges in the image data corresponding to the first image and the second image by selecting candidate edges of the plurality having determined edge lengths greater than an edge length threshold; matching the identified one or more edges in the image data corresponding to the first image to the identified one or more edges in the image data corresponding to the second image; and determining a pixel shift between the image pair based, at least in part, on the matching of edges.
