—We present the Dynamic Programming Projected Phase-Slope Algorithm (DYPSA) for automatic estimation of glottal closure instants (GCIs) in voiced speech. Accurate estimation of GCIs is an important tool that can be applied to a wide range of speech processing tasks including speech analysis, synthesis and coding. DYPSA is automatic and operates using the(More)
We present the DYPSA algorithm for automatic and reliable estimation of glottal closure instants (GCIs) in voiced speech. Reliable GCI estimation is essential for closed-phase speech analysis, from which can be derived features of the vocal tract and, separately, the voice source. It has been shown that such features can be used with significant advantages(More)
Biometrics is the automated method of recognizing a person based on a physiological or behavioural characteristic. Biometric technologies are becoming the foundation of an extensive array of highly secure identification and personal verification solutions. In the last few years there is increasing evidence that technologies based on multimodal biometrics(More)
— In this study, we present a mobile health (m-Health) system that will be used for continuous monitoring of children with suspected cardiac arrhythmias. The system is able to do real-time acquisition and transmission of ECG signals , and facilitate an alarm scheme able to identify possible arrhythmias so as to notify the on-call doctor and the relatives of(More)
—This paper presents an overview of a computer-aided system for the detection of carcinomas in the prostate gland. The proposed system incorporates information from two different types of Magnetic Resonance Images (MRIs), namely the T2-weighted morphological images and the T1-weighted Dynamic Contrast Enhanced (DCE) images, to extract discrim-inative(More)
Cyprus is facing a growing water shortage problem, therefore water losses associated with inefficiencies of the underground water distribution system are not only causing revenue losses for the local water boards but also significantly negatively affect the national water reserves. This paper presents an outline of two research projects, related to each(More)
Biometrics is an automated authentication mechanism that allows the identification or verification of individual based on unique physiological and be-havioural characteristics. The combination of two or more biometric technologies in one application, better known as a multimodal biometric system, can provide enhanced security. Apart from the sound choice of(More)
