Introduction to OpenCV

Now, it's time to introduce OpenCV, or Open Source Computer Vision library, or framework if you will, since OpenCV itself uses them interchangeably and that may also happen throughout this book. However, for the most part we'll simply stick to OpenCV. Well, let's first hear what it really is and then break it down where needed.

OpenCV is an open source and cross-platform library that is used to develop computer vision applications. With a focus on speed and performance, it includes hundreds of algorithms within a variety of modules. These modules are also categorized into two types: the Main and Extra modules. Main OpenCV modules are simply all modules that are built and maintained within OpenCV community, and they ...
