Human Body Detection in an image

I am about to detect human body in video, I have tried peopleDetector, but its not that helpful because it don't detect body all the time I was looking for some efficient algorithm or code through which I can detect human body (either in standing, bending or lying state) so that I can do further processing on it.

No algorithm will work for all possible ways that a person can appear in a video, whether facing away from the camera, wearing a long coat or disguise, very few pixels, squatting or all balled up, not moving, etc. In many cases I imagine that the person will be considered part of the background and be missed. You can go here to search for other algorithms: http://iris.usc.edu/Vision-Notes/bibliography/contents.html, particularly sections 16 and 21.
