+a bw image \, black pixels are considered as background and white poixels
+as foreground.;
+#X text 43 -281 It is useful if you want to detect objects that are
+in front of an static background and you want to isolate the foreground
+siluete of the foreground objects.;
+#X text 43 -173 pdp_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.;
