To respond to Mike's questions, I think I was planning on taking one
picture to get a more accurate area A of the shape of the crowd (if that
possible). The next thing of counting number of people within a smaller
section (say 10 feet^2) means if you stand in the middle or anywhere in
the crowd, you may be able to count number of people around you within 10
feet^2. Then take as many spots as you can, count number of people
around you (within 10 feet^2) everytime, and get the average of all the
trials. Since the area A of the shape and the small section are fixed,
we only need to worry about how people are distributed in the crowd
because people may gather more in the middle and less in the other parts.
I hope these will help to clear something of my method to solve this
problem.
Also, in this problem, they talking about resolution error. I agree with
Mike that this error may be from being unable to distinguish how many
people are in a certain section because the picture is blury... In
addition, according to the document, using computer enhancement, the
center's staff concluded there were 870,000 people present. With margin
of 25% resolution error, the center concluded that up to 1.1 million
(about 870,000 + 870,000*25%) people attended. So 25% may be the
resolution error of the BU's analysis. Please give me some ideas about
this approach and thanks for reading and responding my ideas.
