摘要：

This paper describes an automated approach to register CT and MR brain images, Differential operators in scale space are applied to each type of image data, so as to produce feature images depicting ''ridgeness.'' The resulting CT and MR feature images show similarities which can be used for matching, No segmentation is needed and the method is devoid of human interaction, The matching is accomplished by hierarchical correlation techniques, Results of 2-D and 3-D matching experiments are presented, The correlation function ensures an accurate match even if the scanned volumes to be matched do not completely overlap, or if some of the features in the images are not similar.
