Generalized max/median filtering
Yuan Zou, William T. M. Dunsmuir · 2002
Generalized max/median filtering is defined as an extension of max/median filtering. Properties for these extensions are given. The output distribution of generalized max/median filtering with independent but not identical inputs is derived and applied to the special case of regular max/median filtering thereby providing a new result. Based on these distribution results, it is shown that max/median and generalized max/median filtering can preserve image details.
