1. A method for forming an image of a scene, the method comprising: acquiring a first plurality of sub-images containing image pixels, wherein each sub-image of the first plurality thereof is based on a different portion of the scene, and wherein the first plurality of sub-images includes a first sub-image based on a first portion of the scene and a second sub-image based on a second portion of the scene, and further wherein the first sub-image and second sub-image overlap in a first overlap region; defining a first transformation based on a first correspondence of a first plurality of key features in the first overlap region, the first plurality of key features being in each of the first sub-image and second sub-image; determining a first distortion for improving the first correspondence; and applying the first distortion to each of the first sub-image and second sub-image to form a distorted first sub-image and a distorted second sub-image, where the first distortion is applied to the first sub-image and the second sub-image in equal and opposite fashion.
