Abstract This paper presents a method for automatically detecting line intersections. The underlying application is to detect the road junction locations in map images to serve as control points for warping the images. This method applies a local energy detector to the two dimensions of an image for detecting edges. Also, a new way of using the Hough transform is proposed to facilitate the detection of the appropriate intersection points. This algorithm is integrated with a real application software system, the CRIM Image Mining Environment (CIIvIE), which is being developed for industrial applications.
