Abstract: An extension to the basic concept of correlation detection as a means of image registration is developed. The technique involves linear spatial preprocessing of the inages to be registered prior to the application of a correlation measure. This preprocessing operation utilizes the spatial correlation within each image and greatly improves the detectability of image misregistration. An analysis of the computational aspects of the algorithm is given. Also, results of a computer simulation to evaluate the technique are given.

TL;DR: In this paper, a global linear conformal transformation for each slave picture is used to segment the corresponding image into regions such that, for the implementation of the correction, all pixels within a region can be shifted by the same number of rows and columns.
