This paper considers the development of a monitoring tool based on citizen science, smart-phones and web applications, which allows the community to share information about geolocated wildlife sightings. The data is managed in a web platform, so that various sectors of the community can access, visualize, share and benefit of the generated information. Wildlife sighting data can be used for promoting...
This paper addresses the problem of optimal estimation in a feedback loop where both communication channels, feedback path and control path, are subject to data loss. To deal with measurement loss, the controller embeds a data dropout compensator that replace the missing data with optimal estimates of the measurement. For the case of control signal loss, we consider that the controller sends not only...
This paper describes the current development of a collaborative monitoring tool, via smartphones and Web applications that allows the community to generate and share information about geolocalized sightings of marine fauna. Agencies such as WWF (World Wide Fund for Nature) or other agencies interested in studying the considered species may use the generated data to support their conservation mission,...
Facial expressions are a rich source of communicative information about human behavior and emotion. This paper presents a real-time system for recognition and imitation of facial expressions in the context of affective Human Robot Interaction. The proposed method achieves a fast and robust facial feature extraction based on consecutively applying filters to the gradient image. An efficient Gabor filter...
