Installing libraries

OpenCV is a library with a collection of tools for manipulating pictures and extracting information from them. The name is an abbreviation of Open Computer Vision. The tools are strung together to make useful behaviors and pipelines for processing images. To be able to run our code on the Raspberry Pi, we will need to install the Python OpenCV library there.

We will also install NumPy, the numeric python library. This lets us to do manipulations of large blocks of numbers. An image stored on a computer is essentially a large block of numbers, with each tiny dot having similar content to the three-color numbers we sent to the LEDs in Chapter 9, Programming RGB Strips in Python.

Also, at a Terminal, install the following ...
