–Iris recognition system has proven its capability in implementing reliable biometric security protocols in various high risk sectors like aviation, border patrol and defence. The banking and financial sector has to adoptthis system because of its robustness and the advantages it provides in cutting costs and making processes more streamlined. The technology started out as a novelty however due...

Irises from chick embryos and from 2and 3-week-old chicks were studied using ultrastructural and histochemical methods in order to clarify the relationship between cell loss in the ciliary ganglion and the establishment of permanent peripheral connections between the ciliary neurons and the iris muscle. The iris muscle undergoes morphological and biochemical differentiation between 11 and 13 da...

This paper proposes a new framework to detect, segment, and estimate the localization of eyes from periocular Near-Infra-Red iris image under alcohol consumption. stage will take part in final solution measure fitness for duty. Fitness systems allow us determine whether person is physically or psychologically able perform their tasks. Our segmentation based on an object detector trained scratch...

in the current iris recognition systems, noise removing step is only used to detect noisy parts of the iris region and features extracted from there will be excluded in matching step. whereas depending on the filter structure used in feature extraction, the noisy parts may influence relevant features. to the best of our knowledge, the effect of noise factors on feature extraction has not been c...

The mechanistic study of glaucoma pathogenesis has shifted to seeking to understand the effects of immune responses on retinal ganglion cell damage and protection. Cytokines mediate the biological effects of the immune system, and our previous study revealed an imbalance of T-helper (Th) 1-derived and Th2-derived cytokines in the serum of patients with glaucoma. In this study, we collected iris...

PURPOSE This study was designed to investigate an animal model of uveitis that resembles anterior uveitis in humans after immunization with iris-ciliary body antigen. METHODS Male Lewis rats 6 to 8 weeks of age were immunized with the buffer- and detergent-insoluble bovine iris-ciliary body antigen mixed with complete Freund's adjuvant and pertussis toxin. Antigen was digested with various pr...

PURPOSE To determine the relative density and tissue localization of mRNAs for serotonin (5-hydroxytryptamine; 5HT) receptor subtypes in human ocular tissues and correlate with their possible functions in the eye. METHODS Total RNA was extracted from human ocular tissues samples from multiple donors and transcribed into cDNA. An optimized reverse transcriptase polymerase chain reaction (RT-PC...
