An Ontology-based approach to environmental signature detection with particular reference to navigating vessels is presented. The final attempt will be to check if environmental markers taken from MODIS sensors (hence at moderate spatial resolutions, from 250m up to 1 km) can be reversely associated with the event of a vessel transit or presence. To fulfill this requirement, although at an early stage,...
Detecting human presence automatically is a challenging task since several environmental parameters may affect the quality and the continuity of detection. Although many techniques have been developed so far in the literature to solve this problem, they generally rely on well-defined operational context. Hence, they are sensitive to uncontrolled variables and unpredicted events. In this work an ontology-based...
Aim of this work is to present a new approach to the problem of user presence monitoring in working environments. Particularly, this work is focused on the evaluation of the presence or absence of a user in front of a terminal. This question is of paramount importance in applications requiring the user's presence e.g. video surveillance systems, control centrals, etc. The authors propose a technique...
