    A method for building possible correspondences between the ontologies of two communicating agents is presented, without the need of complete disclosure of their ontologies. The central element of our approach is an abductive argumentative framework allowing to decide the needed and sufficient knowledge to make a decision in the current context and current goal, assuming the existence of a preferen...

    Recognizing and annotating the occurrence of team actions in observations of embodied agents has applications in surveillance or in training of military or sport teams. We describe the team actions through a spatio-temporal correlated pattern of movement, which can be modeled by a hidden Markov model. The hand-crafting of these models is a difficult task of knowledge engineering, even in applicati... View full abstract»

    The increasing number of ontologies of the semantic web poses new challenges for ontology mapping. Ontology mapping in the context of question answering can provide more correct results if the mapping process can deal with uncertainty effectively that is caused by the incomplete and inconsistent information used and produced by the mapping process. We present a novel approach of how Dempster-Shafe... View full abstract»

    Artificial neural networks are known to have strong generalization abilities, but they entirely lack comprehensibility, due to their connectionist nature. Neural network ensembles augment this characteristic, making them less appealing in domains where comprehensibility is as important as accuracy. This paper presents the implementation of a new system based on a method for combining ensembles of ... View full abstract»

    E-business contracts comprise conventions regarding the behavior of the agents, including obligations, rights and permissions. Contract handling refers to contract negotiation, ratification and monitoring. Negotiation and ratification are accomplished through communication protocols. For monitoring purposes, agents have to reason on actions, and their effects on the evolution of the commitments in... View full abstract»

    To develop driving assistance systems which alert the driver in case of inadequate speed according to the visibility conditions, it is necessary to have descriptors of the driver visibility and in particular to detect the visible features in the image grabbed by the camera. In this aim, a hysteresis filter is proposed, which is based on the visibility level (VL) rather than on the gradient magnitu... View full abstract»

    While vision is a directed modality, i.e. constrained to a field of view (FOV), audition is not directed, and humans can localize sound outside their field. Similar to humans, robotic sound localization is of high importance, as it helps the robot to increase the degree of perception of its environment, especially in cases where vision is obstructed by barriers; this might be the case in many resc...

    Stereovision systems mounted in vehicles are generally used by obstacle and lane detection applications with working ranges up to 100 m. The stereo reconstruction process for such depths is a high demanding one, regarding increased accuracy camera parameters. Among the parameters, some of them have a critical influence in the quality of the 3D reconstruction process and need special attention duri... View full abstract»

    A new approach for the detection of curbs (borders of relevant traffic isles, sidewalks, etc) is presented, in the context of urban driving assistance systems. The 3D data from dense stereo is transformed into a rectangular elevation map. The 3D resolution and uncertainty of the stereo sensor are evaluated and used in the detection process. Edge detection is applied on the elevation map in order t... View full abstract»

    Sparse (edge based) stereo reconstruction has been used for many years, being less computational expensive. The dense (all pixels in image) stereo reconstruction, real-time computable nowadays, brings 3D reconstructed points even for less textured image regions, and has a lower percentage of wrong reconstructed points. This article presents novel algorithms for obstacle detection, using dense ster... View full abstract»

    This paper proposes a new approach for a vehicle based pedestrian detection and classification system. The pedestrian detection is performed based on the 3D data by generating a density map. Pedestrian classification uses a pattern matching approach and exploits both 2D image information and 3D dense stereo information. Because 3D information accuracy does not allow the direct classification of th... View full abstract»

    We describe a chamfer based matching algorithm which efficiently search the best match from high number of human templates using distance transformation. The novel part of the algorithm is that we introduce a template space which offers more information to create an optimal templates hierarchy and it can be used directly to track people more efficient as the coarse-to-fine technique. This matching... View full abstract»
