We define morphological operators on weighted graphs in order to speed up image transformations such as floodings, levelings and waterfall hierarchies. The image is represented by its region adjacency graph in which the nodes represent the catchment basins of the image and the edges link neighboring regions. The weights of the nodes represent the level of flooding in each catchment basin ; the weights of the edges represent the altitudes of the pass points between adjacent regions.
