ABSTRACT:
The invention relates to an automatic image analysis method in which two images which have been recorded at different instants are analyzed and a transformation function is determined on the basis of the shifts of image sections, which transformation function describes the shift from one image to another. In order to enable exact determination of this shift, corresponding image sections are determined in the two images by histogram analysis.
