Une nouvelle règle de combinaison répartissant le conflit - Applications en imagerie Sonar et classification Radar A new conflict-redistributing combination rule - Applications to sonar imagery and radar target classification

and key words These last years, there were many studies on the problem of conflict coming from information fusion, especially in evidence theory. We can summarize the solutions for managing the conflict in three different approaches: first, you can try to suppress or reduce the conflict before the combination step; secondly, you can manage the conflict in order to give no influenence to the conflict in the combination step, and then take into account the conflict in the decision step; thirdly, you can take into account the conflict in the combination step. The first approach is certainly the better, but not always feasible. It is difficult to say which approach is the best between second and third. However, the most important is the produced results in applications. We propose here a new combination rule that distributes the conflict proportionally on the elements giving this conflict. We compare these different combination rules on real data in Sonar imagery and Radar target classification.
