Draw Circle, Print Text On An Image | OpenCV Tutorial

In Python OpenCV Tutorial, Explained How to put text and Circle over the image using python OpenCV?

Syntax: cv2.circle(img, center, radius, color[, thickness[, lineType[, shift]]])

.   The function cv::circle draws a simple or filled circle with a given center and radius.
.   @param img Image where the circle is drawn.
.   @param center Center of the circle.
.   @param radius Radius of the circle.
.   @param color Circle color.
.   @param thickness Thickness of the circle outline, if positive. Negative values, like #FILLED,
.   mean that a filled circle is to be drawn.
.   @param lineType Type of the circle boundary. See #LineTypes
.   @param shift Number of fractional bits in the coordinates of the center and in the radius value.

Draw Circle using OpenCV on NumPy array or Image
