The choroid is a tissue layer at the back of the eye, which can be imaged by optical coherence tomography (OCT). Choroidal thickness has been proven to be correlated to several ophthalmic diseases in several studies. In this paper we proposed a novel segmentation technique to address this challenge. This technique firstly automatically segments the inner boundary of the choroid using a two-stage fast...
Authorization means using techniques to establish identity, based on the knowledge and information you know, have or are. A user name and a password is the knowledge people know, for example. Subscriber Identity Module (SIM) card in your mobile or a security ID card is what people have. Biometrics information, such as iris, fingerprint or face structure are what people are. The main theme of this...
Vanadium, a potent toxic agent and carcinogen, is widely used in industry. Evidences show that exposure to vanadium is associated with an increased risk of lung cancer. But the mechanisms involved are far from fully understood. In this present study, we investigated that exposure of human bronchial epithelial cells (Beas-2B) to vanadium pentoxide resulted in an obvious induction of cyclooxygenase-2...
M-commerce brings challenges for both individuals and society. The creation and maintenance of secure identities for online payment has emerged as an important priority of businesses and consumers. In order to address some of these challenges we implement an efficient biometric mobile payment authorization system combined with an embedded commercial barcode reader to provide a worldwide platform-independent...
In this paper, we solve the fully invariant problem of iris recognition by combining two existing techniques: logarithmic map and MACH filter; each capable of achieving invariance to several of the possible variations of a target object. The out-of-plane rotation invariance is achieved using a maximum average correlation height filter (MACH), and the scale and in-plane rotation invariance is achieved...
