It depends on what you mean by count, and what your images are. Do you want to track people walking through a room? Do you want to estimate the crowd size, like at a stadium or big outdoor event, via overhead photos? There could be a million different possibilities, but you haven't given even one. Or even posted a photo. Surely you must know something about your photos or videos. Didn't whoever hired you to do this supply you with imagery? If you shared something you'd probably get a better answer.

count number of students in the class !!

I'd probably use a template along with a reference image. Subtract the images and look inside the template locations (seats) to see if the difference is big enough to indicate that a student is sitting there.

I have something similar - a demo to check an OMR test for what circles the student filled in. See attached.

That is quite difficult to do. See http://www.mathworks.com/matlabcentral/answers/?term=tag%3A%22detect+human%22

You indicate you need to count students in a class, but remember that

• chairs might be re-arranged
• additional chairs might be brought in for large groups
• some students might stand
• some students might be in wheel-chairs
• some students might put their bags down in chairs
• some students might bring in robots or pets or service animals
• some students might be in costume
• some of the people inside the class might not be students
