Getting started

All of the code in this book is targeted for OpenCV 4.2 and has been tested on Ubuntu 18.04. Throughout this book, we will make extensive use of the NumPy package (http://www.numpy.org).

Additionally, this chapter requires the UnivariateSpline module of the SciPy package (http://www.scipy.org) and the wxPython 4.0 Graphical User Interface (GUI) (http://www.wxpython.org/download.php) for cross-platform GUI applications. We will try to avoid further dependencies where possible.

For more book-level dependencies, see Appendix A, Profiling and Accelerating Your Apps, and Appendix B, Setting Up a Docker Container.

You can find the code that we present in this chapter at our GitHub repository here: https://github.com/PacktPublishing/OpenCV-4-with-Python-Blueprints-Second-Edition/tree/master/chapter1.

Let's begin by planning the application we are going to create in this chapter.
