Paper Abstract

Computer vision inspection systems are widely used for on- line inspection and quality control to improve the finished product quality and lower the costs. In this study, a carrier grating is used to carry spatial information about defects. To demodulate the regular/irregular fringe information, a Gabor-filter demodulation method is proposed, which is better for automatically detecting and localizing fringe distortion and hence demodulation method has been implemented for testing some wineglass samples. Using Gabor channel filters the feature images from global to local over those samples regions are extracted and utilized to classify them into good and bad.
