Method for the automatic recognition of an object in an image

To enable a rapid and safe automatic recognition of the position of the catheter, particularly for an electrophysiological examination with an automatic control system of an electrode catheter, a two-stage image evaluation of an x-ray fluoroscopy image is provided. In the first analysis step, frequency polygons are herewith developed as potential locations of the catheter with the aid of structures contained in the image. In the second analysis step, only the previously identified potential catheter positions are investigated with the aid of a template method and the actual catheter position is identified.
