Next, we use the cv2.circle() function to create our circle on this white blank image. 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 w
To create a circle, you first import and read an image, then display or render a circle on that image. We can do it with the help of the imread() method of OpenCV. To this method, we have to pass the absolute image path as an argument. This method will read the provided image an...
