| Abstract(in English) | In this paper, we propose a new method to detect a slanted ellipse using Hough transform with 5 parameters effectively. The procedure is as follow : First, a pair of arcs is detected as a part of the slanted ellipse as the result of a circle detecting Hough transform with 3 parameters ; then the central point (x_c, y_c) and the slanted angle θ can be obtained. Second, the slanted ellipse is transformed into a normal ellipse whose central point is (0, 0) and slanted angle is zero degree. Two parameters of a normal ellipse, the major axis and the minor axis (a and b) can easily be obtained by 2 parameters Hough transform. Thus, the slanted ellipse can be detected with less memory and less data processing. |
