It seems to be working on other simpler images like that of a circuit board. Imshow("Hough Circle Transform Demo", src_gray) NamedWindow("Hough Circle Transform Demo", CV_WINDOW_AUTOSIZE) (min_radius & max_radius) to detect larger circlesįor (size_t i = 0 i < circles.size() i++) HoughCircles(src_gray, circles, CV_HOUGH_GRADIENT, 1, 10,ġ00, 30, 1, 30 // change the last two parameters / Apply the Hough Transform to find the circles I am using opencv HoughTransform and I can't find parameters that make this work.
