*NOTE* This project is done by a group of students from Singapore Polytechnic.
The tools and components were provided by our FYP supervisor Teo Shin Jen.
This project is an expansion from the laser trip wire gun project shown here - http://www.instructables.com/id/Building-a-Sentry-Gun-with-Laser-Trip-Wire-System-/?ALLSTEPS
The only difference is that the gun will not be triggered by laser but by a face.
Basically, this project is combining face tracking and the laser trip wire gun, thus, a face tracking gun.
The algorithm used for face tracking is similar to the one done by techbitar - http://www.instructables.com/id/Face-detection-and-tracking-with-Arduino-and-OpenC/?ALLSTEPS
In order to implement face tracking, openCV is used. OpenCV(open source computer vision) is a library of programming functions for real time computer vision. Their library can be found : http://opencv.willowgarage.com/wiki/
