9.1 You See What in that Image?

Once a digital picture has been formed and processed, it's still only a bunch of numbers until we have a computer that displays it for us to see. But, as Hamlet would say, there's the rub. What we see is actually a collection of lit-up dots on the display, but our brain processes these dots to form the image in our head. One person can look at the displayed image and say, "What a cute puppy!" Another person can look at that same collection of lit-up dots and say, "Are you sure that's not a cat?" Thus begins our journey into the interpretation of images.
