VISUAL INSPECTION OF CERAMIC TILES USING PIXELS PAIR DIFFERENCE

The texture feature extraction method could be used in ceramic tiles machine visual inspection. The ordinary method of visual inspection in ceramic tiles production process is performed by human vision. The results are inhomogeneous tile classes and rather slow and boring inspection. There are papers which describe methods developed for quality inspection of ceramic tiles but these demand a lot of computing power or do not achieve acceptable efficiency. For testing purposes good and defective ceramic tiles of complex texture are scanned. Results described in this paper show that the approach which combines pixels pair difference with first order statistical coefficients could be used in visual defect detection system.
