Abstract
Images of glass product that are captured under poor light usually make defected regions covered by dark pixels because of refraction and scattering brought about by defects on glass. On the other hand, image texture makes it unlikely to effectively identify defects accompanied by some texture by using commonly-used image segmentation and defects extraction algorithms. Watershed segmentation algorithm is proposed in this paper to extract catchment basin where defects characteristics in each image region will be calculated with the twofold application of gray level co-occurrence matrix(GLCM) and parameters characteristics . Defects will be finally identified using shape operator.
