Thewidespread use of mobile devices with Internet connectivity has resulted in the storage and transmission of sensitive data. This has heightened the need to perform reliable user authentication on mobile devices in order to prevent an adversary from accessing such data. Biometrics, the science of recognizing individuals based on their biological and behavioral traits, has the potential to be ...

In present day world when identity circumferences many social, personal, professional outlooks, the identification of identity is highly critical. In pursuit of the same if we consider biological identity of person as a resource to identify his identity, we are approaching towards a new arena of a metric system call biometric system which enables us for automatic identification of an individual...

This paper presents an efficient iris segmentation algorithm. It uses an improved circular Hough transform to detect the inner boundary and the integro-differential operator to detect the outer boundary of iris from a given eye image. Search space of the standard circular Hough transform is reduced from three dimensions (center coordinates and radius) to only one dimension, which is the radius....

Iris segmentation is an important phase in iris recognition and identifies the accuracy of preprocessing. This paper proposes improved peak detection algorithm to locate the pupil accurately. The modified peak detection algorithm determines the optimal peak wh ich helps for pupil localization. Thresholding is done based on the peak determined. Finally canny edge detector is applied on the binar...

Iris segmentation is a process to isolate the accurate iris region from eye image for recognition. on non-ideal and noisy images with active contour. Nevertheless, it currently unclear how contour responds blurry or motion blur, which presents significant obstacle in segmentation. Investigation images, especially initial position, rarely published must be clarified. Moreover, evolution converge...

This paper present a pupil detection/segmentation algorithm for iris images based on Structure Tensor analysis. Eigenvalues of the structure tensor matrix have been observed to be high in pupil boundaries and specular reflections of iris images. We exploit this fact to detect the specular reflections region and the boundary of the pupil in a sequential manner. Experimental results are given usi...
