It contains optimized code written in C++ and has binding for Python and Java. Considering the versatility of OpenCV, we will be using it to explain computer vision algorithms. Most of the code in this book is in Python, except for external repositories. OpenCV can be set up in two ways depending on how we will use it. We will begin with the easy way.
