Parameters Creates a vertical or horizontal Scharr operator. Parameters See also Scharr Creates a separable linear filter. WebMorphological filters are based on the mathematical morphology theory, which has a wider application in geometrical metrology aside from surface filtration. This chapter illustrates two advanced algorithms based on computational geometry, which enables a morphological filter to be applied to free-form surfaces.
