Once you have the frame, you have the job of figuring out exactly what "yellow" means. For example you might be doing quality control on a conveyer, wanting to allow the yellow lemons to pass, but rejecting the lemons that are still green. Or perhaps the camera is a security camera that is required to record security badges, but must not record yellow security badges because those are used to signal clandestine visits that are "off the record".
