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.

Python implementations and Python distributions

A Python implementation is a program that acts as the Python programming language interpreter. The interpreter provided by https://www.python.org/ and the one that comes with Linux is known as CPython. Other popular implementations include (but are not limited to) the following:

  • MicroPython
  • IronPython
  • Stackless Python
  • Jython
  • PyPy
  • CircuitPython

We can find a list of alternative implementations and their project URLs at https://www.python.org/download/alternatives/.

A Python distribution is a Python interpreter implementation and an additional set of packages bundled together. A few Python implementations are distributions themselves. Actually, there is no clear distinction between the terms implementation and distribution. We can find more information about distributions at https://wiki.python.org/moin/PythonDistributions.
