Segmentation of Printed Circuit Board Images into Basic Patterns

摘要

Segmentation is the first and foremost step in the inspection of theprinted circuit boards. In this paper a new technique for the segmentation of printed circuit board (PCB) images is presented. The technique basically segments a given PCB into small windows containing primitive PCB subpatterns. The technique proposed exploits the simplicity and the homogeneity of the PCB images and is inherently parallel. A detailed discussion of the experiments and the results obtained is also presented.
