Biometric technologies rely on specific biometric characteristics that are used for recognition. The particular characteristic for a given situation can be described through a serious of descriptive parameters including ease of collecting, permanence, measurably, acceptability, deceptiveness, universality, uniqueness, sample cost, system cost, database size, as well as environmental factors. By...
Background: The aim of this study was to highlight the structural changes in patients with cataract following surgery and repercussions on anterior pole. Methods: A total 83 diagnosed who underwent uneventful phacoemulsification included. Every patient examined one week prior two weeks after surgery. Pre- postoperative assessment included examination posterior segment, keratometry, optical biom...

-Security is a major issue in Automated Teller Machine (ATM).with the wide spread utilization of electronic transactions it is necessary to increase customers recognition accuracy. Biometric systems can offer convenient and secure mode of authentication to the customers. This paper proposes a survey of how multimodal biometric system enhances level of security in ATM system. Multimodal biometri...
Introduction In our research we present the idea of reliable multimodal biometric system that combines the analysis of 3D facial information and palm blood vessel pattern. The increasing verification of result reliability is based on multidimensionality and advanced acquisition of the biometric data. Multidimensionality includes the combination of two or more biometric parameters in one system ...
The performance of biometric recognition systems can become limited in operating environments due to the presence of extraneous noise factors. Biometric fusion alleviates this problem by consolidating information from various biometric sources, thereby achieving a higher recognition rate. One challenge faced in fusion is how to optimally combine information originating from the different source...
PURPOSE To examine the impact of parental astigmatism on astigmatic error and ocular biometric parameters in children. DESIGN Population-based cross-sectional study. METHODS Six-year-old children (n = 1,741; 78.9% response) and 12-year-old children (n = 2,367; 75.3% response) underwent a comprehensive eye examination, including cycloplegic autorefraction and ocular biometry. Astigmatism was...
