mmmh, your response is certainly true..but consider this problem :
I have 300 frames of a Man against a blue background. Bacuase of lighting and
camera resolution etc..the Background *IS NOT* a constant RGB value.
I want to Composite the man onto another image.
What I do know is that Blue will be the dominant color in the
background…However, just replacing pixels where B>G and B>R won't work
because blue eyes will become background colour *AND* the shadow of the man on
the blue background is lost! This appears to be quite a tricky piece of logic
and I can't figure it out..
….*YET*
..Video Post will only cut it if the area outside of the man is a solid
consistent color. VP will let me do Luma keying, but as far as I can make out,
true ChromaKeying is not possible.
