TY - CONF T1 - Modeling and generalization of discrete Morse terrain decompositions T2 - Proc. 20th Int. Conf. on Pattern Recognition, ICPR Y1 - 2010 A1 - De Floriani, Leila A1 - Magillo,P. A1 - Vitali,M. AB - We address the problem of morphological analysis ofreal terrains. We describe a morphological model for a terrain by considering extensions of Morse theory to the discrete case. We propose a two-level model of the morphology of a terrain based on a graph joining the critical points of the terrain through integral lines. We present a new set of generalization operators specific for discrete piece-wise linear terrain models, which are used to reduce noise and the size of the morphological representation. We show results of our approach on real terrains. JA - Proc. 20th Int. Conf. on Pattern Recognition, ICPR VL - 10 ER -
