Paper Abstract

We address the problem of predicting the propagation of forest fires, by estimating the local direction of the wind. Since the wind direction depends on many local factors, we propose to use aerial photographs and to analyze the shape of the smoke. First, a classification is performed with a learning strategy in order to identify pixels located in the smoke area. Then, we give algorithmic details of the computation of the medial graph, used to describe the shape of the smoke. Finally, the wind direction is given by the direction of edges along the nodes of the longest path of the medial graph. Interesting results illustrate the method.
