Detailed Description

Morphology filter.

Library: ilvbmpflt

This bitmap filter lets you perform fattening or thinning on an image. This filter uses a kernel to compute component-wise minimum or maximum values to set the new component value.

Member Enumeration Documentation

enum IlvMorphologyFilter::Operator

This enumeration defines the possible values for the operation mode.

Enumerator
Erode	Erode The filter erodes (thins) the source image. This is the default.
Dilate	Dilate The filter dilates (fattens) the source image.
