How to calculate number of protesters

0

Is there any technique to help the press to make the protesters count as read a story here and was shown three research and among them is one that comes to give a 6 million difference and 300,000 counting the" Data Sheet "to" organizers ".

So was wondering if there is any program that does this count through photos or video, I found far this " margin of error ."
