Introduction to OpenCV, OpenNI, and PCL

Let's look at the software frameworks and libraries that we will be using in our robots. First, let's look at OpenCV. This is one of the libraries that we are going to use in this robot for object detection and other image-processing capabilities.

What is OpenCV?

OpenCV is an open source, BSD-licensed computer vision library that includes the implementations of hundreds of computer-vision algorithms. The library, mainly intended for real-time computer vision, was developed by Intel Russia's research, and is now actively supported by Itseez (https://github.com/Itseez). In 2016, Intel acquired Itseez.

OpenCV is written mainly in C and C++, and its primary interface is in...
