ABSTRACT

The approach for formal description of topological description of images is suggested. It
is based on the grammar approach for the definition the different types of graphic
images. The procedure for verification of defined image is developed. It is based on the
conformity checks.
The procedures for creation of such description from binary maps and grey level
monochrome or multiband images are compared. The procedures for matching of
identical points in images are introduced.
Such approach is suitable for georeferencing of aerial or satellite images by usage of
coordinate information from digital maps. It is part of common procedure for
rectification of georeferenced images.
