Paper Abstract

This paper describes an image recognition system designed to inspect the standards quality of electronic assemblies. The essence of the present algorithm is the location of electronics components, at the input image, that disrupt the acceptance requirements for the manufacture of printed circuit board assemblies, which have been adopted by association connecting electronics industries. To this end, image processing modules, based on a nonlinear composite filter are employed with the objective to discriminate between the electronics components that meet the acceptance condition and those that are in defect condition. The proposed recognition system is based on nonlinear composite filter, which is obtained from a training set of reference images. Then, the optimal filter is used in a digital correlator, which results in a simple and robust inspection system.
