Eye Blink Related

edit

Hi, I am new to opencv and I need help. I am working on Ubuntu and programming in C and I have detected the single eye blink of a person. Now I want to make a blinking pattern such that if a person blinks continuously (3 times in 3-4 seconds) the pattern is recognized.

I have thought of a logic but dont know how to implement it.

1. Store the start & end time of the blink in 2 arrays.
2. Then check the end time of a second blink and subtract it from start time of the first blink. Set a threshold of 3-4 seconds.
3. If subtraction is more than threshold, discard it, if not go for the next blink.
4. If 3 blinks found in 3-4 sec called it as pattern found.

I am new to C also, so it would be great if somebody could help me out. Thanking in anticipation.
