Member Function Documentation

§ Get() [1/2]

template<class TImage >

GenericFastLinearImageGradientFunction2D< TImage >::GradientType mirtk::GenericFastLinearImageGradientFunction2D< TImage >::Get	(	double	x,
		double	y,
		double	z = `0`,
		double	t = `0`
	)		const

inlinevirtual

Get gradient of given image at arbitrary location (in pixels)

This function is used to interpolate the image value at arbitrary locations when no extrapolator was set.

Reimplemented from mirtk::GenericFastLinearImageGradientFunction< TImage >.

Definition at line 42 of file FastLinearImageGradientFunction2D.hxx.

§ Get() [2/2]

template<class TImage >

template<class TOtherImage >

GenericFastLinearImageGradientFunction2D< TImage >::GradientType mirtk::GenericFastLinearImageGradientFunction2D< TImage >::Get	(	const TOtherImage *	input,
		double	x,
		double	y,
		double	z = `0`,
		double	t = `0`
	)		const

inline

Get gradient of given image at arbitrary location (in pixels)

If the location is inside the finite domain of the image, an actual image instance can be passed as first argument directly such as an instance of GenericImage. Otherwise, an image function which extends the finite image domain to an infinite lattice is needed, i.e., an instance of a subclass of ExtrapolateImageFunction.

Definition at line 60 of file FastLinearImageGradientFunction2D.hxx.

§ GetInside()

template<class TImage >

GenericFastLinearImageGradientFunction2D< TImage >::GradientType mirtk::GenericFastLinearImageGradientFunction2D< TImage >::GetInside	(	double	x,
		double	y,
		double	z = `0`,
		double	t = `0`
	)		const

inlinevirtual

Evaluate image gradient without handling boundary conditions

This version is faster than EvaluateOutside, but is only defined inside the domain for which all image values required for interpolation are defined and thus require no extrapolation of the finite image.

Reimplemented from mirtk::GenericFastLinearImageGradientFunction< TImage >.

Definition at line 78 of file FastLinearImageGradientFunction2D.hxx.

§ GetWithPadding() [1/2]

template<class TImage >

GenericFastLinearImageGradientFunction2D< TImage >::GradientType mirtk::GenericFastLinearImageGradientFunction2D< TImage >::GetWithPadding	(	double	x,
		double	y,
		double	z = `0`,
		double	t = `0`
	)		const

inlinevirtual

Get gradient of given image at arbitrary location (in pixels)

This function is used to only interpolate foreground image values. If fully outside the foreground region, the _DefaultValue is returned.

Reimplemented from mirtk::GenericFastLinearImageGradientFunction< TImage >.

Definition at line 51 of file FastLinearImageGradientFunction2D.hxx.

§ GetWithPadding() [2/2]

template<class TImage >

template<class TOtherImage >

GenericFastLinearImageGradientFunction2D< TImage >::GradientType mirtk::GenericFastLinearImageGradientFunction2D< TImage >::GetWithPadding	(	const TOtherImage *	input,
		double	x,
		double	y,
		double	z = `0`,
		double	t = `0`
	)		const

inline

Get gradient of given image at arbitrary location (in pixels)

This function is used to only interpolate foreground image values. If fully outside the foreground region, the _DefaultValue is returned.

If the location is inside the finite domain of the image, an actual image instance can be passed as first argument directly such as an instance of GenericImage. Otherwise, an image function which extends the finite image domain to an infinite lattice is needed, i.e., an instance of a subclass of ExtrapolateImageFunction.

Definition at line 69 of file FastLinearImageGradientFunction2D.hxx.

§ GetWithPaddingInside()

template<class TImage >

GenericFastLinearImageGradientFunction2D< TImage >::GradientType mirtk::GenericFastLinearImageGradientFunction2D< TImage >::GetWithPaddingInside	(	double	x,
		double	y,
		double	z = `0`,
		double	t = `0`
	)		const

inlinevirtual

Evaluate image gradient without handling boundary conditions

If the location is partially inside the foreground region of the image, only the foreground values are interpolated. Otherwise, the _DefaultValue is returned.

This version is faster than GetWithPaddingOutside, but is only defined inside the domain for which all image values required for interpolation are defined and thus require no extrapolation of the finite image.

Reimplemented from mirtk::GenericFastLinearImageGradientFunction< TImage >.

Definition at line 100 of file FastLinearImageGradientFunction2D.hxx.

§ GetWithPaddingOutside()

template<class TImage >

GenericFastLinearImageGradientFunction2D< TImage >::GradientType mirtk::GenericFastLinearImageGradientFunction2D< TImage >::GetWithPaddingOutside	(	double	x,
		double	y,
		double	z = `0`,
		double	t = `0`
	)		const

inlinevirtual

Evaluate image gradient at an arbitrary location (in pixels)

If the location is partially inside the foreground region of the image, only the foreground values are interpolated. Otherwise, the _DefaultValue is returned.
