The synergistic combination of single standing methods for the efficient and effective solution of complex problems represent the next level of research the last two decades in the area of computer vision and image understanding, due to their complicated challenges. Many of these combinations are based on the human researcher's experimental studies and most recently on a semi-automated or automated...
This work describes two new pause detection algorithms and compare their performance with four standard voice activity detection (VAD) methods represented by the adaptive long term spectral divergence (LTSD) algorithm, the likelihood ratio test (LRT) algorithm, the neural network thresholding and G.729. The proposed algorithms exploit the concept of adaptation in order to handle adverse conditions...
The deployment of wearable health monitoring systems (WHMS) is expected to address several important healthcare-related issues such as increasing healthcare costs, the rising number of the elderly population and treatment of chronic conditions. However, most of the currently developed WHMS simply serve as ambulatory physiological data loggers and transmitters in order to make the recorded bio-signals...
In this paper we present an enhanced version of our NRF spectra classifier based on local-global graphs (LG-graphs) and provide a comparison with other possible alternative detection schemes. Experimental results verify our claims that the proposed nuclear resonance fluorescence (NRF) signature detection methodology is favorable over other widely employed conventional feature extraction and signal...
