OpenCV is a free open source library used in real-time image processing. It's used to process images, videos, and even live streams, but in this tutorial, we will process images only as a first step. Before getting started, let's install OpenCV. Install OpenCV.

Parameters: image: It is the image on which rectangle is to be drawn. start_point: It is the starting coordinates of rectangle. end_point: It is the ending coordinates of rectangle. color: It is the color of border line of rectangle to be drawn.

Step 1: Import OpenCV. Step 2: Define the radius of circle. Step 3: Define the center coordinates of the circle. Step 4: Define the color of the circle.

To do it, we simple need to use the imread function, passing as input the path of the image in the file system. Now, to draw a circle on the image, we simply need to call the circle function of the cv2 module.
