Abstract
This project presents a method to analyze and detect defects on the
surface of a master disc, the cause of distorted images by applying
a neural network program and micro-image technology. The referred
method or system automatically, step by step detects defects in the
disc electrical signal output to drive a x-y table and provide
indicative information for managing contamination in a cleanroom of
a manufacturing plant.
Subject terms: neural network; digital image processing.
