Proceedings ArticleDOI
SLIC: Short-length iris codes
TL;DR: It is shown through experiments that the regions close to the pupil and sclera contribute least to discrimination, and that there is a high correlation between adjacent radial rings.
Journal ArticleDOI
Recognizing Disguised Faces in the Wild
TL;DR: The disguised faces in the wild (DFW) dataset as discussed by the authors contains over 11,000 images of 1000 identities with variations across different types of disguise accessories, including impersonator and genuine obfuscated face images for each subject.
Proceedings ArticleDOI
An efficient, two-stage iris recognition system
TL;DR: This paper shows how to use a short-length iris code to pre-screen a large database and thereby reduce the number of full comparisons needed to a fraction of the total and can reduce the cost and/or time needed by an order of magnitude with very little impact on identification performance.
Proceedings ArticleDOI
A new approach for iris segmentation
TL;DR: Overall matching accuracy can be improved by rejecting images which have a low quality assessment, thus validating the utility of this measure.
