Industrial image processing by means of an image recognition integrated system

An overview of the requirements for industrial applications of computer vision is given. A method called multilevel input binary template matching, which applies binary template matching to gray-level images, is presented. With this method, a vision system can be tailored to the difficulty of the individual computer-vision application while maintaining high speed and high reliability in all cases. A full custom VLSI specially designed for binary template matching is discussed. This dedicated VLSI chip, called IRIS, has a configurable kernel up to a size of 1024 elements for 1-D or up to 32×32 elements for 2-D, and has integrated line buffers. Some application examples from the field of industrial automation are presented
