OpenCV (Open Source Computer Vision Library) is an open-source computer vision and machine learning software library. It provides various tools and functions for image and video analysis, manipulation, and computer vision tasks. OpenCV is primarily written in C++ but has bindings for Python, making it accessible and widely used in the Python programming language.
To use OpenCV in Python, you need to install the OpenCV library and its Python bindings. You can do this using pip, Python’s package manager, as follows:
bashCopy codepip install opencv-python
Once you have OpenCV installed, you can start using it in your Python programs. Here’s a simple example of loading an image and displaying it using OpenCV:
pythonCopy codeimport cv2
# Load an image from a file
image = cv2.imread('image.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 from a file called ‘image.jpg,’ displays it in a window, waits for a key press, and then closes the window. OpenCV provides a wide range of functions for image processing, computer vision, and machine learning tasks, such as image filtering, object detection, and facial recognition.
