OpenCV (Open Source Computer Vision Library) is a popular Python library for computer vision tasks. It provides tools and functions for various computer vision tasks, such as image and video manipulation, object detection, face recognition, and more. To use OpenCV in Python, you need to install the library and then import it into your Python code. Here are the basic steps:

1. Install OpenCV:
   You can install OpenCV using pip, the Python package manager, with the following command:

   pip install opencv-python

If you want to include additional modules (e.g., OpenCV-contrib modules), you can install them separately.

2. Import OpenCV in your Python code:

   import cv2

Now you can use OpenCV functions to perform various computer vision tasks. Here’s a simple example of how to load an image and display it using OpenCV:

import cv2

# Load an image from file
image = cv2.imread('example.jpg')

# Display the image in a window
cv2.imshow('Image', image)

# Wait for a key press and then close the window
cv2.waitKey(0)
cv2.destroyAllWindows()

This code loads an image named ‘example.jpg’ from the current directory, displays it in a window, waits for a key press, and then closes the window.

OpenCV provides a wide range of functions and capabilities for more advanced computer vision tasks. You can refer to the official OpenCV documentation and tutorials for detailed information on how to use OpenCV for specific tasks: https://docs.opencv.org/
