Facial Recognition Computer Vision Libraries OpenCV dlib Installation cmake This is simple enough. But it’s worth calling out individually. If you do deep work with these binaries then you will start to mess with cmake. It’s a bit tough to build binaries. https://cmake.org/install/ apt-get install cmake Install dlib on Ubuntu The easiest way to install dlib is to install it with the bundled version with pip. It may end up that you will need to compile dlib.

Biometrics From Wiki: Biometrics is the technical term for body measurements and calculations. It refers to metrics related to human characteristics. Biometrics authentication (or realistic authentication) is used in computer science as a form of identification and access control Let the conspiracy theories abound.

USB HID Relay USB Relay on Ubuntu Linux I am starting off with this hardware: KNACRO 4-Channel 12V USB Control Switch Relay Module This was fairly easy but not where I wanted to be. I found a library that did a ton of things for me. Thank you to @darrylb123 for https://github.com/darrylb123/usbrelay There was a python contribution but it broke the build. I spent a few hours trying to get it to build and gave up and just smashed the ugly.
