This paper describes a method to register four images that cover a larger area. One image needs to have an overlapping region with an adjacent one. The process uses a two stage register. The first stage, called the local register stage, involver the matching of control points over two adjacent images and the register of these points. This provides a local matching point (the centroid of all control points) and the local register angle. This is done for each overlapping region. Since there are calculation errors in the local matchings, the four matching points way not agree with each other. Then the need of the second stage appears. This second step uses a minimization function to achieve the best position considering all of the four local matching points and their local angles. The function tries to force the points to agree and also tries to preserve the local register parameters.
