Figure 1: A trainee, who interacts with objects to perform the procedure, within the virtual environment, supervised by the trainer ABSTRACT The use of Virtual Environments for Training is strongly stimulated by important needs for training on sensitive equipments. Yet, developing such an application is often done without reusing existing components, which(More)
In this article, we present a parallel image processing system based on the concept of reactive agents. Our system lies in the oRis language, which allows to describe ÿnely and simply the agents' behaviors to detect image features. We also present a method of segmentation using a multi-agent system, and two biological applications made with oRis. The(More)
oRis is a toolkit for interactive simulation : it is both an object-based concurrent programming language and an execution environment. Its features make oRis a generic platform for multiagent systems (MAS) implementation. It is a dynamically interpreted language, instance-grained which allows the user, during the execution, to observe the MAS, to interact(More)
The advent of the computer and computer science, and in particular virtual reality, offers new experiment possibilities with numerical simulations and introduces a new type of investigation for the complex systems study: the in virtuo experiment. This work lies on the framework of multi-agent systems. We propose a generic model for systems biology based on(More)
In this paper we present an algorithm for the detection of fish otolith growth rings based on a graph construction method. The identification of growth rings, for age estimation, is routinely achieved in fishery laboratories by human readers. One of the major problem encountered during an automatic image processing is the lack of ring continuity perception.(More)
In the context of biological complex systems multi-agent simulation, we present an interaction-agentmodel for reaction-diffusion problems that enables interaction with the simulation during the execution, and we establish a mathematical validation for our model. We use two types of interaction-agents: on one hand, in a chemical reactor with no spatial(More)
