Description

gen_struct_elementsgen_struct_elementsGenStructElementsGenStructElementsGenStructElements serves to generate eight structuring elements normally used in the operator fittingfittingFittingFittingFitting. The default value 'noise'"noise""noise""noise""noise" of the parameter TypeTypeTypeTypetype generates elements especially suited for the elimination of noise.
