This paper presents an example of employing visual information processing technologies for detecting and measuring rings in banknote images. The size of the rings is one of parameters used to inspect the banknote printing quality. The approach developed consists of two phases. In the first phase, based on histogram processing and data clustering, image areas containing rings are localized and edges of the rings are detected. Then, in the second phase, applying the hard and possibilistic spherical shell clustering to the extracted edge pixels the ring centre and radii are estimated. The experimental investigations performed have shown that even highly occluded rings are robustly detected. Several prototypes of the system developed have been installed in two banknote printing shops in Europe.</p> http://dx.doi.org/10.1016/j.engappai.2004.09.014 http://hh.diva-portal.org/smash/record.jsf?searchId=1&pid=diva2:237440 371 3 Engineering applications of artificial intelligence Journal Paper 363 Detecting and measuring rings in banknote images 18 2005 2016-09-30T20:39:10Z 2457662.3605324 Detecting and measuring rings in banknote images 500 0 plainlist list 1 [[:Publications:Detecting and measuring rings in banknote images]] Detecting and measuring rings in banknote images# QUERY6262401e1771fcc024e2c98bc07815c7 500 [2,"smw-datavalue-property-restricted-annotation-use","Publisher"] Detecting and measuring rings in banknote images# ERR6c155b5d70b69ddb590b4f2e73389c2a 500 [2,"smw-datavalue-property-restricted-annotation-use","Author"] Detecting and measuring rings in banknote images# ERRe24f17e090c98448f3de99d03182b7b6
