In this paper, we name the images obtained by mapping dots from defect inspections as secondary images. We propose a method of extracting informations for specifying the causes of distinctive structural patterns that appear in the secondary images. We suggest a light process in order to obtain a real time inspection and feature extraction process at the same time. The patterns that appear in the secondary images are lines, aggregated patterns which we call ``islands", and random dots. In this study we focus on the recognition of ``island" patterns. Our method is robust to the variation of average dot densities of the secondary image and the recognition results can be adjusted to the recognition results of skilled mechanics. |
