Nowadays, biometric recognition and verification methods are everywhere, trying to face the security issues that constantly affect our digital-every day life. In addition, many special-purpose applications, also need a constant (continuous) …
Context awareness is major component of Ambient Intelligence. In fact, Ambient Intelligent environments are designed to combine ubiquity, awareness, intelligence and natural interaction. Awareness is defined as the ability by the system to locate and …
One of the problems for archaeologic museums is having the opportunity to show most of the objects that they preserve. This is an action they can’t afford because of the limitation of exhibition spaces, the high number of artifacts they guard and/or …
Biometric recognition is often affected by low quality images. This is especially true in iris recognition fields, due to the fact that the area of the iris is quite small and wrong detection are very common when standard iris detection methods are …
The new frontier of biometrie authentication exploits wearable sensors. At present, there is no need of special equipment. Both cameras of increasing resolution, and MEMS-based sensors (Micro Electro-Mechanical Systems) are ubiquitously embedded in …
The iris segmentation step is usually the most time consuming stage of biometric systems when dealing with non ideal conditions, which produce diverse noise factors during the acquisition. On the other side, it also represents a crucial step since …
This paper presents a novel approach to hand-based biometrics that uses mobile devices. Hand-based recognition has been explored via different research lines and taking into consideration different traits. On the other hand, few studies tackle its …
Nowadays, many smartphones are provided with built-in sensors for the acquisition and the recognition of specific biometric traits of the user. This policy has been adopted since the massive use of such devices brought the user to store sensible data …
Facial recognition at-a-distance in surveillance scenarios remains an open problem, particularly due to the small number of pixels representing the facial region. The use of pan-tilt-zoom (PTZ) cameras has been advocated to solve this problem, …
Efforts in biometrics are being held into extending robust recognition techniques to in the wild scenarios. Nonetheless, and despite being a very attractive goal, human identification in the surveillance context remains an open problem. In this …
