A Frequency-based Approach for Features Fusion in Fingerprint and Iris Multimodal Biometric Identification Systems
2010
The basic aim of a biometric identification system is to discriminate automatically between subjects in a reliable and dependable way, according to a specific-target application. Multimodal biometric identification systems aim to fuse two or more physical or behavioral traits to provide optimal False Acceptance Rate (FAR) and False Rejection Rate (FRR), thus improving system accuracy and dependability. In this paper, an innovative multimodal biometric identification system based on iris and fingerprint traits is proposed. The paper is a state-of-the-art advancement of multibiometrics, offering an innovative perspective on features fusion. In greater detail, a frequency-based approach result…
An Embedded Module for Iris Micro-Characteristics Extraction
2009
In this paper a new approach, based on iris micro-characteristics, has been used to make possible an embedded biometric extractor. This recognition approach is based on ophthalmologic studies that have proven the existence of different micro-characteristics as well as fingerprint minutiae. These micro-characteristics are permanent and immutable and they can be used to create strong and robust identification systems.Biometric recognition systems are critical components of our everyday lives. Since such electronic products evolve to software intensive systems, where software, becoming larger, more complex and prevalent, introduces many problems in the development phases. The development of em…
A Dynamic System for Personal Communications: The Opportunistic Chat
2007
most of currently available inter-personal instant messaging systems are client-server based. Users of such systems need to be connected to some centralized entity which goal is to supply them with information needed to make the communication possible, such as the list of connected users, their status, and the address of their devices. Our proposed system for an “Opportunistic Chat” allows people to exchange written messages over Bluetooth and (if necessary) TCP/IP connections, with no need of any kind of centralized entity, by using ad-hoc procedures, automatically selected and operated. Such system can be accessed almost from any kind of device, either mobile or not, ranging from personal…
PARLARE E INTERAGIRE CON UN ROBOT UMANOIDE. TRA MENTE NATURALE E MENTE DIGITALE
2020
L’interazione sociale tra uomini e robot umanoidi è uno dei temi sui quali si focalizza attualmente la ricerca tenendo presente che l’interazione risulta efficace quando prevede anche la decodifica dei segnali non verbali e gestuali normalmente a corredo dei segnali verbali di comunicazione. Di seguito verranno illustrate quali capacità deve esibire un robot umanoide per percepire, dialogare e interagire socialmente con esseri umani, utilizzando sia segnali non verbali sia i bio-segnali cerebrali dell’uomo rilevati attraverso un caschetto BCI. I paradigmi di cooperazione umano-centrici per definire i ruoli sociali che un robot umanoide potrà avere domani nella società degli esseri umani son…
Homomorphic Approach to RF-Inhomogeneity Removal Based on Gabor Filter
2007
In this paper a bias correction algorithm for magnetic resonance imaging (MRI) is presented. The magnetic resonance (MR) images affected by this artifact, also called RF-inhomogeneity, exhibit irregular spatial brightness variations caused by magnetic field inhomogeneity. Here we present an original algorithm based on E2D - HUM, already proposed by some of the authors, where a modified Gabor filter is introduced in the elaboration chain to provide directional capabilities to suppress the artifact. The process of restoration doesn't care about the structure of the image and it has been applied to MR images of different parts of body like knee, abdomen, pelvis and brain. A comparison with oth…
Intelligent Management Systems for Energy Efficiency in Buildings: A Survey
2014
In recent years, reduction of energy consumption in buildings has increasingly gained interest among researchers mainly due to practical reasons, such as economic advantages and long-term environmental sustainability. Many solutions have been proposed in the literature to address this important issue from complementary perspectives, which are often hard to capture in a comprehensive manner. This survey article aims at providing a structured and unifying treatment of the existing literature on intelligent energy management systems in buildings, with a distinct focus on available architectures and methodology supporting a vision transcending the well-established smart home vision, in favor o…
Inferring Business Rules from Natural Language Expressions
2014
This paper proposes a mapping technique for automatically translating rules expressed in a format based on natural language, i.e. Semantics of Business Vocabulary and Business Rules (SBVR) standard, into production rules that can be executed by a computer (i.e. Rule engine). The proposed approach achieves a twofold purpose: on the one hand non IT skilled people (i.e. Domain expert) can effectively focus on business rules definition by using statements in natural language, and on the other hand the IT staff will have to manage business rules in a format ready to be executed by a rule engine. The main goal is to overcome some weaknesses in the software development process that could produce i…
Experiences with CiceRobot, a Museum Guide Cognitive Robot
2005
The paper describes CiceRobot, a robot based on a cognitive architecture for robot vision and action. The aim of the architecture is to integrate visual perception and actions with knowledge representation, in order to let the robot to generate a deep inner understanding of its environment. The principled integration of perception, action and of symbolic knowledge is based on the introduction of an intermediate representation based on Gardenfors conceptual spaces. The architecture has been tested on a RWI B21 autonomous robot on tasks related with guided tours in the Archaeological Museum of Agrigento. Experimental results are presented.
MetaMeth: A tool for process definition and execution
2006
Nowadays, several different tools are used in Software Engineering; in this work we are mainly interested to those supporting the design phases. These are usually classified in three categories: CASE, CAME, CAPE tools. MetaMeth is a CAME and a CAPE tool at the same time
