Converting Color video to grayscale using OpenCV in Python
OpenCV is a huge open-source library for computer vision, machine learning, and image processing. It can process images and videos to identify objects, faces, or even the handwriting of a human. In this article, we will see how to convert a colored video to a gray-scale format.
- Import the cv2 module.
- Read the video file to be converted using the cv2.VideoCapture() method.
- Run an infinite loop.
- Inside the loop extract the frames of the video using the read() method.
- Pass the frame to the cv2.cvtColor() method with cv2.COLOR_BGR2GRAY as a parameter to convert it into gray-scale.
- Display the frame using the cv2.imshow() method.
Example: Suppose we have the video file CountdownTimer.mov as the input.
