ABSTRACT:
In a method of binarizing images containing linear structures, and particularly images of prints from the skin, areas are determined that are each distinguished by a preset approximate direction of the structures. The areas of the image that are determined are each filtered with a Gabor filter adapted to the given direction. The method according to the invention can advantageously be implemented into a system for analyzing and binarizing images containing linear structures, and particularly images of prints from the skin. Such systems can advantageously be used for identifying human individuals and are especially intended for access control and the like.
