1. A computer-implemented method comprising: receiving a first and a second image of an object, the images taken from different locations; identifying the location of a set of points from the first image, the set of points indicating features of interest relative to a first image plane; identifying the location of a set of points from the second image, the set of points indicating features of interest relative to a second image plane; identifying argument values initially for a transform function, the transform function configured to map the location of the set of points relative to the first image plane to the location of the points relative to the second image plane; iteratively refining the transform function arguments; and outputting the transform function arguments.
