Abstract

We propose to conceive a distributed image analysis system, according to a multi-agents approach. We are especially interested in the first steps system, (image pre-processing and segmentation). We introduce a new segmentation system obtained by the co-operation of a robust edge detector of canny type and a region growing. The cooperation technique allows exploiting the advantages of each method to reduce the drawback effects of the other one. A multi-agents approach provides an increased flexibility, by separating the various expertises within the system. Each agent is responsible for a precise task and its interactions with other agents are carried out by well defined protocols. Such an implementation makes the system development easier as well as later modification. The developed architecture allows carrying out in parallel a lot of system processes. The system consists of several agents executed as independent processes on several machines connected on a heterogeneous network and communicating through message passing using PVM.
