CGAL::Feature_graph::AmbrosioTortorelli_on_image< Vector_3 > Struct Template Reference

#include <CGAL/Feature_graph/AmbrosioTortorelli_on_image.h>

Definition

template<typename Vector_3>
struct CGAL::Feature_graph::AmbrosioTortorelli_on_image< Vector_3 >

Class that evaluates the Ambriosio-Tortorelli normals and sharpness measure from an image.

Two functors can then be retrieved to access the estimations.

Template Parameters

Vector_3

the type of the normal vector model of Kernel::Vector_3.

Is model of

NormalEstimator

Types
typedef Vector_3	Normal_type
	The type of the normal vector.
typedef unspecified_type	Sharpness_functor
	The type of the functor that allows to retrieve the sharpness values.
typedef unspecified_type	Normal_functor
	The type of the functor that allows to retrieve the normals.

Constructor
template<typename Image , typename FT = Sharpness_functor::Sharpness_value_type>
	AmbrosioTortorelli_on_image (const Image &image, const FT &selection_threshold=FT(0.25))
	evaluates the normal and sharpness values using the Ambrosio-Tortorelli energy optimization.

Functor Accessors
Sharpness_functor	sharpness_functor () const
	returns the functor that allows to retrieve the sharpness values.
Normal_functor	normal_functor () const
	returns the functor that allows to retrieve the normals.

Constructor & Destructor Documentation

AmbrosioTortorelli_on_image()

template<typename Vector_3 >

template<typename Image , typename FT = Sharpness_functor::Sharpness_value_type>

CGAL::Feature_graph::AmbrosioTortorelli_on_image< Vector_3 >::AmbrosioTortorelli_on_image	(	const Image &	image,
		const FT &	selection_threshold = FT(0.25)
	)

evaluates the normal and sharpness values using the Ambrosio-Tortorelli energy optimization.

Template Parameters

Image	the image type model of FeatureImage_3
FT	a model of RealEmbeddable

Parameters

image	the image.
selection_threshold	a threshold on the sharpness value. Elements with a sharpness value lower than this threshold are considered flat and will be given a negative value.
