In the middle of the night one sometimes turns over to see a (boogey) man standing in the bedroom but it will be, upon further thought, just a coat hanging on a coat hanger.
When algorithmically determining what a machine will imagine is there in an image it is not normal to include boogey men in the list of possible things the machine might imagine. However it is always necessary for the machine to imagine something. It forms an object hypothesis. Anything in the image that is inconsistent with the object hypothesis is simply deemed as unknown.
The human brain does not appear to immediately relegate inconsistencys as unknowns. It will continue to imagines all sorts of things, whether it tests such for consistency or not. The last thing it will do is give up on imagining what is there in the image.
But my algorithms give up immediately. Where it can register what is there it will do so and but everything else is assigned to the set of unknown things in the image.
