Abstract :
We present a hierarchical method to match regions in image sequences based in graph theory. First, we build a graph representation for each image, the so-called tree of critical lakes, used in the multiscale watershed. In a second step, assignments between regions in subsequent images are accomplished through maximum clique detection in a association graph
