Abs t rac t . This paper presents a method I for tracking and segmenting vehicles in a traffic scene. The approach is based on a frame to frame segmentation followed by a tracking process. As opposed to usual segmentation methods, our method feedbacks segmentation with tracking information for improving results. Several facilities are provided for traffic monitoring such as vehicles trajectorie...

[1] We extend the theory of climate feedbacks to include atmospheric chemistry. A change in temperature caused by a radiative forcing will include, in general, a contribution from the chemical change that is fed back into the climate system; likewise, the change in atmospheric burdens caused by a chemical forcing will include a contribution from the associated climate change that is fed back in...

The paper is concerned with a general optimization problem for a nonlinear control system, in the presence of a running cost and a terminal cost, with free terminal time. We prove the existence of a patchy feedback whose trajectories are all nearly optimal solutions, with pre-assigned accuracy.

The high potential of P2P infrastructures for enterprise services and applications both on the intranet (e.g. project workgroups) and on the Internet (e.g. B2B exchange) can be fully achieved provided that robust trust and security management systems are made available. This paper presents the reputation system we have devised for our P2P framework which supports secure rolebased peergroups and...

Positive systems possessing %rst integrals are considered. These systems frequently occur in applications. This paper is devoted to two stabilization problems. The %rst is concerned with the design of feedbacks to stabilize a given level set. Secondly, it is shown that the same feedback allows to globally stabilize an equilibrium point if it is asymptotically stable with respect to initial cond...

The purpose of this project is to develop a platform for human-robot and human-humanoid interface. One application of this platform is to study the impact of the feedbacks provided by the robot and the humanoid on the interaction. Several studies have shown the benefit of verbal and non-verbal analysis and synthesis for the improvement of Human-Agent Interaction and of HumanRobot Interaction (H...

This paper deals with the convergence aspect of diffusive delay Lotka-Volterra systems with infinite delays. It is well known that such a system has a globally asymptotically stable steady state if the negative feedbacks of the intraspecific competitions are dominant and instantaneous. It is shown here that such a globally asymptotically stable steady state continues to exist even if the instan...

In this paper, explicit amplitude and frequency expressions for a Cellular Neural Network with an Opposite-Sign Template (CNN-OST) under oscillation condition are derived and a novel inductorless oscillator circuit with negative feedbacks, based on this simple structure is designed and implemented. The system is capable of generating quasi-sine signals with tuneable amplitude and frequency whic...
