Python cv2 rectangle: Draw a Rectangle using OpenCV

To draw a rectangle in Python using OpenCV, use cv2.rectangle() function. The cv2 rectangle() method is used to draw a rectangle on any image.

OpenCV is a programming library aimed at real-time computer vision. OpenCV-Python is the main library of Python that is specifically designed to solve computer vision problems. Suppose you are working on Machine Learning projects than you often come across the scenario when you need to identify the specific object from the image. In this case, you need to draw a rectangle around a particular object to distinguish from other objects of the image.

To separate that object, you need to draw a rectangle around that, and there OpenCV-Python library comes to the rescue.

Create a Virtual Pen and Eraser with Python OpenCV - Genial Code

Learn Free how to create a virtual pen and eraser with python and OpenCV with source code and complete guide. This entire application is built fundamentally on contour detection. It can be thought of as something like closed color curves on compromises that have the same color or intensity, it's like a blob. In this project we use color masking to get the binary mask of our target color pen, then we use the counter detection to find the location of this pen and the contour to find it.
