and the compare each incomming frame with that. On the output you get
a bw image \, black pixels are considered as background and white poixels
as foreground.;
#X text 27 -94 pix_opencv_bgsubstract :: A simple background substract
and binarization object.;
#X text 26 -49 It is useful if you want to detect objects that are
in front of an static background and you want to isolate the foreground
silhouete of the foreground objects.;
#X text 26 59 pix_opencv_bgsubstract works comparing color values of
each pixel \, so it can fail if the foreground object has the same
color that the background \, and also if the light conditions or the
shadows changes since you SET the background image.;
