I hope someone could push me in the right direction.. Basically I'm trying to do this..http://www.sparkfun.com/products/8630
It doesn't make sense to me how an IR sensor and a camera could "sense" a person and that person's movement..
I have the thought that the Arduino needs to understand what a blank sidewalk "looks" like and then compare that image to one when someone walks by..
But then when a person is within the field of vision, how can I track a person's movement forward and back. That is very confusing..
ANY help is MUCH appreciated..
