Yes! It shouldn't be too hard to implement either, compared to depth detection.

  Actually I would say it is a hard problem. Look at anything filmed in a studio against a blue/green screen. This is with perfect lighting, a perfectly racked camera, a proper camera tripod/dolly, a perfectly even background screen, the presenter wearing safe colours and anything else I forgot to mention controlled. Now look at the fine hair detail. Does it resolve too well in front of the keyed in <weathermap>? Probably not. You need a very highly skilled operator to get the fine hair detail right. Hollywood can afford the pros, a regional news station in Papua New Guinea maybe not so. I would not say fine hair detail is out of the question, however, we might have to live without it when using this faux depth affect for now.

    It doesn't seem to be the same league of problem. Because you are going to blur the stuff in the background anyway, you can be agressive with the masking and the blurring will make it imperceptible. With blue/green screens you are making changes much more severe than just blurring (in terms of the colors, hues and shades involved). Source: Hardly an expert, but I am quite a photography geek, and I've done some work on this type of graphical algorithms in the past (not this type of fancy 3D stuff though).
