It’s due to the Hough circle detection is a method to detect the circles in the image and video. Before joining the show, Goodman, 78, was a judge on “Strictly Come Dancing,” a British version of “Dancing With the Stars. circle(cir, (i[0], i[1]), i[2], (0, 255, 0), 2, cv2. around(circles)) # 把circles包含的圆心和半径的值变成整数 cir = img. Richard Hough, and Alexis Klimoff (New York: Collier Books, 1975), p. ” A former professional ballroom dancer himself, Goodman, who has seen. The transform effectively searches for objects with a high degree of radial symmetry, with each degree of symmetry receiving one "vote" in the search space. hough circles
