Machine vision technology: past, present and future

Discusses the past, present, and future of machine vision technology, emphasizing its practical aspects. Four types of machine vision technology based on pattern matching, feature parameter, window, and slit-light methods are now being widely used in industry. However, recent applications require more effective use of knowledge-based processing, combined with application-specific methods. Study is thus required for the future progress of machine vision, especially in such areas as sensor fusion, real-time processing, and visualization/enhancement technology. Some new future applications are also discussed
