Well pick one that doesn't rely on moving people, if that's your case. I know they've used it for still crowds, like to estimate the number of people at events and demonstrations, like in Washington DC. It became a heated argument because one group wanted to have a million people and estimates showed only 400,000 which made them angry because they needed a million to match the name of their event. Since that event, the National Park Service will not give crowd estimates anymore.

"....The National Park Service estimated the attendance at the original 1996 march to be around 400,000, but subsequent counts by private organizations put the number at 800,000 or higher. The National Park Service has refused to give crowd estimates on Mall activities since...."
Anyway, why can't you do a calibrated area fraction like I suggested? Post your image if you want.
