The first parameter that we must feed into the cv2.circle() function is the image we want to draw it on. We will be using what we created with numpy, whiteblankimage. This provides a perfect clean white background, in which we can place our circle shape. The second parameter we must ...

Now, we have to store the data returned by the imread() inside a variable named image as this will be used in the circle() method. Code Snippet: image = cv2.imread("img.jpg") circle_coordinates = (400, 250) radius = 60 colour = (255, 255, 0) thickness = 5 img_with_circle =...
