You can do a background subtraction on a video of the person in the actual location to get all the foreground pixels corresponding to her/him. And then replace the corresponding foreground pixels of another video (traffic, restaurant, etc.) with these pixels. It would be in real-time, but maybe not so clean. Hope this helps.
