Eigenvalues of the structure tensor matrix have been observed to be high in pupil boundaries and specular reflections of iris images. We exploit this fact to detect the specular reflections region and the boundary of the pupil in a sequential manner. Experimental results are given using the CASIA-IrisV3-Interval database (249 contributors, 396 different eyes, 2,639 iris images). Results show that our algorithm works specially well in detecting the specular reflections (98.98% success rate) and pupil boundary detection is correctly done in 84.24% of the images.</p> SSBA Symposium 2011 (SSBA2011), 17-18 mars, Linköping, Sweden http://hh.diva-portal.org/smash/record.jsf?searchId=1&pid=diva2:408372 4 Conference Paper 1 Iris Pupil Detection by Structure Tensor Analysis 2011 2016-09-30T20:40:38Z 2457662.3615509 Iris Pupil Detection by Structure Tensor Analysis 500 0 plainlist list 1 [[:Publications:Iris Pupil Detection by Structure Tensor Analysis]] Iris Pupil Detection by Structure Tensor Analysis# QUERY7f49959e2492863a4b106fa6f23c8858 500 [2,"smw-datavalue-property-restricted-annotation-use","Publisher"] Iris Pupil Detection by Structure Tensor Analysis# ERR6c155b5d70b69ddb590b4f2e73389c2a 500 [2,"smw-datavalue-property-restricted-annotation-use","Author"] Iris Pupil Detection by Structure Tensor Analysis# ERRe24f17e090c98448f3de99d03182b7b6
