Determining whether something in an image is human or not is very very difficult. You are likely to have a very high failure rate for a Halloween party held at Madame Tussaud's Wax Museum

If they're not moving, it's tough. You can probably find skin color, though that's also tough, especially dark skinned individuals. Remember four years ago when some ignorant idiots claimed that HP was making racist cameras because it could automatically find the faces of white people but not black/brown people? http://www.pcmag.com/article2/0,2817,2357429,00.asp

You can try this demo in the Computer Vision System Toolbox: http://www.mathworks.com/products/computer-vision/description4.html.

Yes the humans in the video are moving.The background is static.I just need to segment the humans.Can I do the segmentation for the video as whole or by converting the videos to frames and subtracting each frame individually.

Is that Dalek suit occupied by a small human or is it being remotely controlled? The first is to be detected, the second is to be ignored.

See my demo, attached below. It may help some. It does differencing of the current frame with N prior frames averaged together.
