Iris Recognition Without Iris Normalization
Problem statement: In any real time biometric system processing speed and recognition time are crucial parameters. Reducing processing time involves many parameters like normalization, FAR, FRR, management of eyelid and eyelash occlusions, size of signature etc. Normalization consumes substantial amount of time of the system. This study contributes for improved iris recognition system with redu...
متن کاملThe ND-IRIS-0405 Iris Image Dataset
The Computer Vision Research Lab at the University of Notre Dame began collecting iris images in the spring semester of 2004. The initial data collections used an LG 2200 iris imaging system for image acquisition. Image datasets acquired in 2004-2005 at Notre Dame with this LG 2200 have been used in the ICE 2005 and ICE 2006 iris biometric evaluations [1,2]. The ICE 2005 iris image dataset has ...
متن کاملIris varix simulating an iris melanoma.
Iris varix is rare and little is known about its clinical characteristics. We treated a thrombosed iris varix that simulated an iris melanoma. A 53-year-old man developed a dark brown iris mass and hyphema in his left eye. Ultrasound biomicroscopy revealed a circumscribed mass of the iris stroma. Because of suspicion for melanoma, it was removed by sector iridectomy. Histopathologic examination...
متن کاملshape adaptive, robust iris feature extraction from noisy iris images
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...
متن کاملIris Recognition
In an eye image, the iris is bounded by the pupil opening on its interior and the white sclera on its exterior. The visible iris pattern is largely determined by a meshwork of muscle ligaments. The iris pattern is a promising biometric characteristic because it is thought to be unique to each eye, with a high degree of discrimination ability [1]. In fact the left and right irises from the same ...
