An adaptive method for image registration

摘要

The paper deals with the registration of images with non-linear local geometric distortions. It describes a new approach to the determination of a mapping function from given coordinates of control points. The processed image is recursively divided into subregions of various size and shape according to the distortion character. Each subregion is then transformed by a simple local transformation. The described method enables the registration with optional accuracy. A practical use of this method is presented and a comparison of its accuracy and computing complexity with previously published methods is given.
