WebbDetect ellipses, ovals in images with OpenCV python [SOLVED] Hello everyone, I am using opencv to detect shapes that look like circles, my script reads a png image (center_cut.png) and perfectly detects the circles with their centroids, however when I pass another image where the circles are no longer perfect does not recognize them (left_cut). WebbPerform an elliptical Hough transform. Input image with nonzero values representing edges. Accumulator threshold value. Bin size on the minor axis used in the accumulator. Minimal major axis length. Maximal minor axis length. (default None) If None, the value is set to the half of the smaller image dimension.
