[theora-dev] Seperating Forground from Background

[Kevin Atkinson]

One thing I have noticed when encoding VCDs is that often videos with 
complex backgrounds don't compress nearly as well as those with simple 
ones.  Part of the problem is that TV cameras seam to have the focus so 
that the entire image is clear rather than focusing on the foreground (and 
blurring the backgrounds).  The result is that a good number of bits are 
wasted trying to perfectly encode the background and as a result the 
foreground image suffers.

I was wondering if there is any way to separate the foreground objects from 
the background so that more bits can be spend on the foreground.  Is this 
sort of thing even remotely possible?
