WebThe most straightforward way is to loop over the contour points manually, and draw a circle on the detected contour coordinates, using OpenCV. Also, we use a different image that will actually help us visualize the results of the algorithm. New image to demonstrate the CHAIN_APPROX_SIMPLE contour detection algorithm. WebAfter filtering the contours with the area threshold, you need to check the number of edges of contour, which can be done using: cv2.approxPolyDP (), for a circle len (approx) must be > 8 but < 23. Or you may apply some more sophisticated operations to detect circles here. tricog health limited
