1. A method comprising: selecting a first set of points in a first image, the first set of points located in an overlap region of the first image and a second image; determining a set of tie points in the second image, each tie point correlating to a point in the first set; determining a second set of points, each point in the second set located at a position in the overlap region between a point in the first set and a tie point correlated to the point in the first set; and warping the first image and the second image by applying an algorithm using the second set of points, the algorithm to reposition at least a portion of points in the first image and at least a portion of points in the second image.
