Perhaps; either way, I reckon the algorithm I pointed to would do the job.
Randy? Can you give some more detail about what you're after.
Ciao,

I think Randy's after "blue screen" and "chroma key".
I regret that I have else little to offer on the subject.

Randy,
The keywords I'd use are "flood fill" and "graphics gems".
There was a series of books called "Graphics Gems" that have some
wonderful algorithms for, er, graphics.
Google throws up:
http://www.codeproject.com/gdi/QuickFill.asp
as the first hit, it looks like a decent tutorial. I'm not sure it's
precisely what you're after, but it might give you a start.
Ciao,

Randy,
I think the first problem is defining what is "background". You can do it
in Photoshop very easily because it's defined. Otherwise for a general 2-D
image without layers it's a lot tougher.

What is a good image algorithm that will convert a background of one color
to another? One that will handle edge effects on the border between the
background and the rest of the image?
