Color-defect classification for printed-matter visual inspection system
Proceedings of the 4th World Congress on Intelligent Control and Automation (Cat. No.02EX527) - Tập 4 - Trang 3261-3265 vol.4
Tóm tắt
An automatic defect classification method that pays attention not only to shape-defects but also to color-defects as well is proposed for a printed-matter visual-inspection device. The required characteristic of the shape-defect classification is to have an automatic select function of the feature variable which removes the unnecessary characteristics-parameter space to use few learning data efficiently. The characteristic of the color-defect classification is to identify an abnormal printing-device roller such as rotary press based on the color difference signal with the background color and the UCR process. We evaluated the proposed method with good result.
