iris recognition is one of the most reliable methods for identification. in general, itconsists of image acquisition, iris segmentation, feature extraction and matching. among them, iris segmentation has an important role on the performance of any iris recognition system. eyes nonlinear movement, occlusion, and specular reflection are main challenges for any iris segmentation method. in this pa...

Background: A number of ocular biometric parameters, iris hiotologic and anatomic characters have been suggested as inciting factors for converting patients with narrow angle to angle-closure glaucoma. This study was conducted to determine if there was any goniscopic difference between patients with acute angle-closure glaucoma (AACG) and chronic angle-closure glaucoma (CACG). Methods: ...

Ruizhe Wang*, Matthias Hernandez*, Jongmoo Choi, Gérard Medioni Computer Vision Lab, IRIS University of Southern California Abstract In this paper, we address the problem of both face and body modeling using a single fixed low-cost 3D camera (e.g. Kinect). Unlike other scanning technologies which either set up multiple sensors around a static subject or scan the static subject with a hand-held ...

I present my research on combining cryptography and iris biometrics. This is work with Ross Anderson and John Daugman. It is a short talk so I will leave out the technical detail. The motivation of the research is to incorporate advanced biometric authentication features into cryptography. We find that cryptography lacks the involvement of a human factor. In authentication, you would use a pass...

BACKGROUND Concerns about the immune reconstitution inflammatory syndrome (IRIS) remain a barrier to antiretroviral therapy (ART) initiation during antituberculosis treatment in co-infected patients. OBJECTIVE To assess IRIS incidence, severity, and outcomes relative to the timing of ART initiation in patients with HIV-related tuberculosis. DESIGN Randomized, open-label clinical trial. (Cli...

conclusions physicians should be aware of this rare site of metastasis. early diagnosis is of paramount importance in order to effectively prevent the significant morbidity this condition can cause if left untreated. introduction small cell carcinoma constitutes the most aggressive type of lung cancer, with the greatest propensity for early disseminated disease. although commonly neglected due ...

In view of the limitation of traditional identification, it is easy to lose and copy keys, cards or ID cards, and it is easy to forget the password. Here, an embedded application system was designed based on the iris identification technology, the functions of gathering, inputing, and registering the iris information and identification can be realized. The system architecture was designed by us...

An iris based biometric recognition system provides identification of an individual based on a unique feature or characteristic possessed by that individual. Iris recognition is consider as the most reliable and accurate biometric identification system. In this paper we explore the performance of the iris based recognition system. We take iris image of ten different people and after segmentatio...
