public class JDialogHoughEllipse extends JDialogBase implements AlgorithmInterface, ItemListener, WindowListener
Dialog to create Hough transform with p, q, r1, r2, and theta output for ellipse detection in binary image, where p is the x coordinate of the ellipse center, q is the y coordinate of the ellipse center, r1 is the semimajor axis (or major radius), r2 is the semiminor axis (or minor radius), and theta is the angle of the major axis with the x axis.
