Motion Detection and Object Tracking Plugins

Name	Type	Description	Warnings
stemkoski Motion Detector	Node.js, shinobi-stemkoski.js	This is a method for reading differences in frames with the node-canvas. The method was made by @stemkoski on github, hence the name.	Region Detector does not seem to work correctly. Full frame detection works.
OpenCV Object Tracker	Node.js, shinobi-opencv.js	This is an object tracker interfaced through a Node.js wrapper.	Frame input is limited to 1 fps or you will get Segmentation errors causing the plugin to crash.
OpenCV Object Tracker	Python, shinobi-opencv.py	An attempt at copying the the node.js version by moeiscool.	Currently does not work. Process will not stay alive for requests.
CCV.js Object Tracker	Node.js, shinobi-ccv.js	Currently only a face detector. The current cascade can be replaced.	Uses a lot of CPU power, like a lot.

Why aren’t these just integrated?

Not everyone uses motion detection or object tracking and the libraries required can be bothersome to install based on the OS. For example if I make shinobi-opencv.js a feature then everyone will be required to install OpenCV 2.4 just to use basic features in Shinobi. This also allows us to swap the plugin with a custom one or run it on another machine entirely. Sharing the work between multiple machines can be a great way to optimize performance.
