Here is a short summary of the software and hardware requirements:

• OpenCV version 4.1.x (4.1.0 or 4.1.1 will both work just fine).
• Python version 3.6 (any Python version 3.x will be fine).
• Anaconda Python 3 for installing Python and the required modules.
• You can use any operating system—macOS, Windows, or Linux-based—with this book. We recommend you have at least 4 GB RAM in your system.
• You don't need to have a GPU to run the code provided with the book.
