#X text 9 92 [pix_background] 'removes' the background of an image
by comparing a static image in memory to an incoming video stream.
all values withing a given range are turned black. for best effect
\, place a camera on a static scene like a blank wall and hit 'reset'.
then set the range control to cover any variance in the background.
when a new object enters the scene it will be the only thing draw against
a black background. use pix_chroma_key or pix_compare to add in images
in place of the black.;
