The cv2.findContours() and cv2.drawContours() functions were used to find and draw the contours, respectively. Each contour on the output image was drawn with a random color outline and then displayed one at a time by looping over the contours found.
(np.random.randint(0,255), np.random.randint(0,255), np.random.randint(0,255)) was used to generate a random BGR tuple. The ...
