SEGMENTATION OF PRINTED-CIRCUIT BOARD IMAGES INTO BASIC PATTERNS

Segmentation is the first and foremost step in the inspection of the p rinted circuit boards, In this paper a new technique for the segmentat ion 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 t he homogeneity of the PCB images and is inherently parallel, A detaile d discussion of the experiments and the results obtained is also prese nted, (C) 1998 Academic Press.
