I have one big problem. Let me explain. I have one project, where I need to count number of people on the stadium or in the class, but that code must work for every other image. How to do it? Thank you.

Actually, I've always found that my fingers are pretty good for
counting.
And when you get to the end of your fingers, you just increment the
tens by one and start back at the beginning again.

I'd get an image (from the same viewpoint) of the stadium when it's
totally empty, then subtract the image when it's filled with people.
Take the absolute value, then threshold to get a binary image. Do a
little clean up (e.g. size filtering) and then call bwlabel(). One of
the outputs of bwlabel is the number of objects in the binary image.

How do you count people who are not fully visible? For example, how
would you process something relatively simple such as "The Vanishing
Leprechaun Puzzle" ?
