Breakdown points and optimal soft morphological filtering
Pertti T. Koivisto, Heikki J. Huttunen, Pauli Kuosmanen · 2002
A novel filter optimality criterion based on the breakdown point constraint is proposed. The criterion provides a trade-off between noise attenuation and detail preservation. The formulas for the breakdown points of the basic soft morphological filters are derived. The practical applicability of the criterion is empirically studied in connection with the optimization of soft morphological filters by simulated annealing and genetic algorithms.
