Abstract: In this paper a problem of image matching is considered. We consider the matching of images, which represent the same scene recorded by different sensors. In this paper we discuss problems arising when there are uninformative areas on the images, in which points matching errors occur frequently. In the proposed technology a projective transform is constructed from reliable corresponding points in an informative area. And then this transform is used to determine and adjust the corresponding points in an uninformative area. Experimental results illustrate the effectiveness of the proposed technology.

Keywords: image processing, image informativity estimation, image matching, projective transform, Delaunay triangulation, affine transform.
