You want to determine the size of an object *in* the picture? — Christian Schnorr, Oct 20 '12 at 07:18

You could do that only if there is another metric available for you.

For example, user specified that size of particular object on the same picture is 1 meter. So by using simple geometry and math you could calculate other sizes. Without such information your problem could be resolved.
