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; perfoming a smoothing operation on the first image and the second image to produce smoothed image data; determining edge magnitude of the smooth image data based on derivatives along at least a row and a column of pixel luma components in the smoothed image data; determining edge phase of the smoothed image data based an inverse tangent of the derivatives of the pixel luma components; identifying, by one or more processors, one or more edges in the image data based, at least in part, on the edge magnitude and the edge phase of the smoothed image data; 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.
