PROCESSING EDGES

So how does a dumb machine recognise a line when it sees it?
We have, in my system, a sensory #array which is sending in #signals. In my system that means that there will be one #signal from each cell in the #array. A group of these #signals will be received as input by one of the many thousands of #perceptions. So let's consider one of those #perceptions in isolation from the others.
Some of the #signals will be reporting that a bright light has landed on one particular part of the array, while others will be reporting that only darkness has been recorded at another cell in the array. Recall that each #signal has a location associated with it. These locations will be arbitrary. We should not suppose that the array and the locations are laid out in a neat arrangement corresponding to our notion of a cartesian co-ordinate system. They are just arbitrary locations. But each cell will always have the same location information.
Let us further imagine that a broad patch of light has fallen on the array. That means that all the cells in a part of the array, will be sendng very similar #signals to some #perception. The #perceptiion ignores everything else which may be going on elsewhere on the array. The situation is illustrated in the diagram below.

The #perception receives a group of #signals, from a single region of the #array, and all indicating that bright ligght has been detected. The #perception is programmed in those circumstances that a patch of ligght has been deteected from a region with a location stretiing from one location to another.
