rules for edge detection

Sorry but my mathematica trial version has expired so I can not do anything with that code I uploaded. I did not save the images either. Basically, it was just a "smiley" face. Two solid circles for eyes and a solid mouth. I didn't have much imagination or skill to bitmap something more interesting like the shape of Italy.

Interestingly, there are some rules which give the right side edges and some which give left side edges (kind of like a shadow cast from 45 degrees left or right of the birds eye view). Maybe someone with Mathematica can run the code and post the images along with the rule number.

256 CAs as Find Edge Filters

Attached is an image which shows the results of using the Elem. CAs as Find Edge Filters. The left side column of images are the first half of the Elem. CAs. The right side column shows the last half. Sorry I didn't spend time with references to the rule number. When looking at the image just scroll down looking at the left side. Then scroll back up and view the right side images. That will keep you in sync with the rule numbers.
