This is a pen which writes with invisible ink, how to know what's been written by it? We have used opencv library of python to track it and devode the invisible message. This is the raw or original video. Here we are writing something but the pen is without refill. So, it's can write by it's own. we will process this video to see what has been written. Then we starteded tracking the tip of the pen. And we have drawn a green rectangle around the tip of the pen. To track and see the path or position of pen we have drawn dots on the path taken by pen. To see and understand properly what has been written, we have drawn a blue line to join all the red dots. And that's how we have tracked and got to know what was written by invisible ink.
