I am tracking an infrared LED with a simple contour check - it works great. However the LED has a switch and can be turned off - I am needing to know if the switch went off or if the LED just moved out of view of the camera.
I thought I could do something simple with just checking position, but if the led is moved fast off screen, then the last tracked point I get from my detector is on screen... maybe I can just use something like an edge buffer where if the last point is within the buffer range, it's likely off screen now, and not turned off.
