A Robust Approach to Automatic Iris Localization
In this paper, a robust method is developed to locate the irises of both eyes. The method doesn’t put any restrictions on the background. The method is based on the AdaBoost algorithm for face and eye candidate points detection. Candidate points are tuned such that two candidate points are exactly in the centers of the irises. Mean crossing function and convolution template are proposed to filt...
متن کاملA Novel Approach to Iris Localization for Iris Biometric Processing
Iris-based biometric system is gaining its importance in several applications. However, processing of iris biometric is a challenging and time consuming task. Detection of iris part in an eye image poses a number of challenges such as, inferior image quality, occlusion of eyelids and eyelashes etc. Due to these problems it is not possible to achieve 100% accuracy rate in any iris-based biometri...
متن کاملA Fast, Robust, Automatic Blink Detector
Introduction “Blink” is defined as closing and opening of the eyes in a small duration of time. In this study, we aimed to introduce a fast, robust, vision-based approach for blink detection. Materials and Methods This approach consists of two steps. In the first step, the subject’s face is localized every second and with the first blink, the system detects the eye’s location and creates an ope...
متن کاملAn Automatic Approach to Iris Extraction and Recognition
Biometric systems are used for the automatic recognition of a person based on the unique characteristics or features possessed by that person. Many biometric systems are available now–a-days. Iris Recognition System is one of the most consistent and reliable biometric identification system available. Iris Recognition is the recognition of an individual based on iris features. Several methods ha...
متن کاملRobust Iris Recognition in Unconstrained Environments
A biometric system provides automatic identification of an individual based on a unique feature or characteristic possessed by him/her. Iris recognition (IR) is known to be the most reliable and accurate biometric identification system. The iris recognition system (IRS) consists of an automatic segmentation mechanism which is based on the Hough transform (HT). This paper presents a robust IRS i...
