Describes the high performance system counting the total number of fragments of conductive PCB picture, the width of each of which is smaller than some predetermined magnitude, the number of these fragments arising from parasitic holes (shells) of printed conductors and the amount of magnitude, are not caused by shells. Way is based on the formation of regions related items other than the typical geometric signs and their subsequent counting and calculation formulas.

PCB defect detection, a conductive pattern, the binary image, the pixel segment, cluster, shell, section threshold.
