The Hough transform-a new approach

The Hough transform is presently witnessing an increasing Interest (over 200 references in 1995), due to its capacity of finding the parameters of miscellaneous shapes in an image (or signal), for example straight lines, circles, or mote generally conics. The authors propose here an analytical approach which permits the calculation of the theoretical Hough transform on standard images, in the case of the research of straight lines and show its practical application.
