SurfaceLocalMinima
Header: | AVL.h |
---|---|
Namespace: | avl |
Module: | Vision3DStandard |
Finds surface locations characterized by locally minimal heights.
Applications: Detection of characteristic points, usually after some surface transformations.
Syntax
C++
C#
void avl::SurfaceLocalMinima ( const avl::Surface& inSurface, atl::Optional<const avl::Region&> inRoi, bool inConsiderLowlands, atl::Optional<float> inMinHeight, atl::Optional<float> inMaxHeight, float inMinDistance, atl::Optional<const avl::SurfaceLocalExtremaVerification&> inMinimaVerification, atl::Optional<atl::Array<avl::SurfaceExtremum>&> outLocalMinima, atl::Optional<atl::Array<avl::Region>&> outMinimaRegions = atl::NIL )

Optional Outputs
The computation of following outputs can be switched off by passing value atl::NIL
to these parameters: outLocalMinima, outMinimaRegions.
