Parameter Based Presence and Absence Detection for Automated Visual Inspection Applications

Inspection is an important operation for manufacturing industry to ensure the quality and completeness of product getting manufactured. To improve and speed up visual inspection operation automated visual inspection systems are used. Presence absence detection is a visual inspection method to check and ensure that certain feature or component is present in the product getting manufactured. Automated Visual Inspection is widely used in mass production industry and Presence Absence detection method can be used for presence absence detection. The discussed algorithm is a parameter based algorithm and can be successfully used to detect presence or absence of particular component on the product.
