I need help regarding human detection in MATLAB. I need to detection humans in any position(standing upright, lying on the ground etc). The camera will be in aerial view. Which is the best method for human detection for this scenario? Also can I get the code for the same?

Sounds pretty difficult. From an oeverhead photo, how would you know if a black blob is the top the head of someone wearing a black shirt, or just a black patch of ground? You might want to start by searching Vision Bibliography for "crowd estimation" http://www.visionbib.com/bibliography/contents.html

Oh yeah. Its pretty difficult. Just wanted to know if any methods are existing already. Would it make my job easier if I just convert the video to images/frames?

Depends on a lot of things. Is there skin visible? If so, what color? Do you need to handle moving and stationary people? What is the size of the people relative to the field of view? Are there faces visible? How much clutter is there? Does the illumination change a lot, like an outdoor scene, or is it constant, like in an airport? How much clutter is in the scene? I suggest you narrow down the variables and start with something simple, like light skinned people with dark clothing (or vice versa) in a very uniformly colored, clutter free room. Then branch out from there once you get that solved. Or maybe in the link I gave you there are more sophisticated algorithm that can get you started with more complicated scenery right away. I don't know - people tracking is not my field, so check the link.
