Machine vision technology has created a strong interest among research organizations, resulting in many innovative products. Despite this end users have been very skeptical towards machine vision and its robustness in harsh environments. This book presents the results of a national machine vision technology programme aimed at boosting research and putting research results to work in practical industrial applications. The topics to be covered include image acquisition, analysis of surface colour and texture, applications of machine vision in surface inspection and process control, 3-D measurements, and CAD-based machine vision.
