On Pattern Recognition and Quality Control

The application of pattern recognition to quality control is shown. The well-known methodology of conventional quality control is described briefly to illustrate the philosophy of quality measurement. The advantages of adopting the pattern classification approach in quality control (or quality assurance) include on-line quality monitoring without much alteration of existing conventional systems, instant diagnosis of the production process, and ultimately, automatic feedback control of the overall manufacturing process through the development of a corrective control policy.
