In this paper we describe a new technique to create virtual environments using photographs. A mobile robot is used to take pictures automatically, that are used in an image rendering system. Using a mobile robot allows to take photographs of large areas easily and accurately. Our Virtual and Real Robot (ViRBot) System is used to control the movements of a(More)
In this study, we present the results of classification experiments of induced dog barks in different contexts of behaviour. We applied four validation schemes to trained models in order to determine the level of individuals dependency for context classification. We did an analysis based on feature selection techniques to determine the best acoustic(More)
