a simple classification technique to sense and count the eye blinks

What is it about?

Eye blink is a semi-autonomic rapid opening and closing of eyelid which is controlled by the autonomic nervous system of human brain. This normal and most important function of human eye can be embedded with some created (abnormal) sequences to indicate any unusual message. A real time novel algorithm to count the number of eye blinks (RTREB) in a video sequence using eye facet correlation (EFC) is proposed.

Why is it important?

A unique feature is described to extract/sense blinks and the blink pattern can be encoded and used to exert emergency
