             abstract = "A gray-level image can be interpreted as a topographical surface, 
                         and represented by a component tree, based on the inclusion 
                         relation of connected components obtained by threshold 
                         decomposition. Relations between plateaus, valleys or mountains of 
                         this relief are useful in computer vision systems. An important 
                         definition to characterize the topographical surface is the 
                         dynamics, introduced by Grimaud (1992), associated to each 
                         regional minimum. This concept has been extended, by Vachier and 
                         Meyer (1995), by the definition of extinction values associated to 
                         each extremum of the image. This paper proposes four new 
                         extinction values -- two based on the topology of the component 
                         tree: (i) number of descendants and (ii) sub-tree height; and two 
                         geometric: (iii) height and (iv) width of a level component 
                         bounding box. This paper describes efficient computation of these 
                         extinction values based on the incremental determination of 
                         attributes from the component tree construction in quasi-linear 
                         time, compares the computation time of the method and illustrates 
                         the usefulness of these new extinction values from real 
                         examples.",
