Automating Image and Video Files
IN THIS CHAPTER
Flipping, resizing, cropping, and rotating images
Bulk changing image file formats
Grabbing individual frames from video files

Two Python modules will help greatly in this chapter:
- Pillow: Often referred to as

It provides tools for resizing and cropping, applying filters, and other common image tasks. - cv2: This module offers a Python interface to OpenCV (short for Open Source Computer Vision Library), a powerful library designed for computer vision, image processing, and machine learning tasks.
