Claim One:
1. A method of transforming a first image to bring it closer to alignment with a second image, the method comprising: implementing a multiple kernel tracking technique to determine positions of a set of candidate regions of the first image based on a similarity between a set of target regions of the second image and the set of candidate regions of the first image, wherein the target regions of the second image are respectively positioned over the positions of a predetermined set of points of the second image; using at least some of the determined positions of the set of candidate regions to initialize a Lucas Kanade Inverse algorithm; using the Lucas Kanade Inverse algorithm to determine a set of points of the first image which correspond to at least some of the predetermined set of points of the second image; determining parameters of a transformation to be applied to the first image based on an error metric which is indicative of an error between a transformation of at least some of the determined set of points of the first image and the corresponding points of the predetermined set of points of the second image; and applying the transformation to the first image to bring it closer to alignment with the second image.
