Paper Abstract

A round florescent bulb placed around the lens of a CCD camera illuminates a group of carbon resistors. The pictures are passed to a series of feature detectors the outputs of which are sent to a back propagation neural network. Two identical boards were each made with 112 resistors of various colors. Resistors on one board were burned. The network was trained with a test set of about half the good and bad resistors. Results showed 93.8 percent correct when recalling on the untrained half.
