Automated inspection is an important new technology which promises to significantly improve productivity in a variety of applications. Not only is 100% inspection becoming a possibility but also in-place rather than post-process inspection is now being used. The purpose of this paper is to present techniques for shape, form, and texture recognition for the inspection of automotive brake pads. Although the results are preliminary, they indicate the type techniques which could be applied to the inspection of millions of brake pads per year in the U.S. alone. Also, since brake pads contain asbestos, humans could be removed from a harmful environment.
