Overview of this book

Raspberry Pi is one of the popular single-board computers of our generation. All the major image processing and computer vision algorithms and operations can be implemented easily with OpenCV on Raspberry Pi. This updated second edition is packed with cutting-edge examples and new topics, and covers the latest versions of key technologies such as Python 3, Raspberry Pi, and OpenCV. This book will equip you with the skills required to successfully design and implement your own OpenCV, Raspberry Pi, and Python-based computer vision projects. At the start, you'll learn the basics of Python 3, and the fundamentals of single-board computers and NumPy. Next, you'll discover how to install OpenCV 4 for Python 3 on Raspberry Pi, before covering major techniques and algorithms in image processing, manipulation, and computer vision. By working through the steps in each chapter, you'll understand essential OpenCV features. Later sections will take you through creating graphical user interface (GUI) apps with GPIO and OpenCV. You'll also learn to use the new computer vision library, Mahotas, to perform various image processing operations. Finally, you'll explore the Jupyter Notebook and how to set up a Windows computer and Ubuntu for computer vision. By the end of this book, you'll be able to confidently build and deploy computer vision apps.

Understanding Python 3

Python is a high-level, interpreted, general-purpose programming language. It was created by Guido van Rossum and was started as a personal hobby project but has since grown into what it is today. The following is a timeline of the major milestones in the development of the Python programming language:

Guido van Rossum held the title of benevolent dictator for life for the Python project for most of its life cycle. He stepped down from the role in July 2018 and has been part of the Python Steering Council ever since.

You can read more about Python on its home page at www.python.org.

The Python programming language has two major versions—Python 2 and Python 3. They are mostly incompatible with one another. As the preceding timeline shows, Python 2's sunset happened on 31st December 2019. This means that there is no further development of Python 2. Official...
