Note the image with the wolves.  I think the entire exercise is in that photo.  This system seems very good at patterns.  The animals do well when against natural backgrounds.  That&#x27;s because they match those backgrounds.  Even though they are different colours, animals with fur all adopt some form of camouflage.  So their patterns at some level match the patterns of their natural environment.<p>The wolves are rendered well, the flowers not.  Wolves are camo.  Flowers are the opposite.  They want to stand out from the background.  So the machine doesn&#x27;t handle them well.  The green stripe on the truck also fits this.<p>To take this idea forward, look at the image of the puppies against the grass.  They are not camo.  Their colour is the product of breeding, therefore they do not render so well as the wolves.  There might be something useful here to measure whether or not an animal is being viewed in its natural environment.
