Visual inspection system based on the gray scale morphology

Kuczborski, W. and Attikiouzel, Y. (1989) Visual inspection system based on the gray scale morphology. In: Proceedings of SPIE - The International Society for Optical Engineering. Automated Inspection and High-Speed Vision Architectures III, 6 - 7 November, Philadelphia, PA, USA pp. 35-42.


The paper presents a design concept which eliminates two major weaknesses of existing visual inspection systems: (1) narrow application field and (2) inability to process images with poor contrast or noise distortion. Our system combines two basic inspection principles: (1) Feature Extraction and Comparison and (2) Verification of Design Rules. Inspection algorithms are based on gray scale morphology. Our short time goal is a real-time system which can cope with changing inspection objects and does well with complex, low-contrast images. The long-time goal is a rule-based system, able to translate design specifications of an object into an inspection algorithm.
