Detailed Description

template<class VOXEL>
struct Separable4DFilter< VOXEL >

Structure for representing 4D separable filter of arbitrary size in each directions/axis.

This filter is an extension of the concept used in Separable3DFilter . Please, refer there for more detailed information.

Constructor & Destructor Documentation

template<class VOXEL >

Separable4DFilter< VOXEL >::Separable4DFilter

(

)

[inline]

filter lengths

Empty constructor.

template<class VOXEL >

Separable4DFilter< VOXEL >::Separable4DFilter	(	struct Separable4DFilter< VOXEL > const &	f,
		int	mirror = 0
	)

Copy constructor.

If mirror=1 then it makes an identical copy with the only exception that [xyzt]Data are stored in the reverse order in comparison to the original f.[xyzt]Data.

template<class VOXEL >

Separable4DFilter< VOXEL >::~Separable4DFilter

(

)

The desctructor frees allocated memory.

Member Function Documentation

template<class VOXEL >

void Separable4DFilter< VOXEL >::PrintFilter

(

void

)

It prints the content of the structure to the screen.

template<class VOXEL >

void Separable4DFilter< VOXEL >::RemoveAlmostZeros

(

const VOXEL

ZeroThres = 0.0005

)

Set to zero such filter coefficients which are closer to the zero than ZeroThres.

All axes, if present, are scanned and compared to the same threshold.

template<class VOXEL >

void Separable4DFilter< VOXEL >::RemoveAlmostZeros	(	const VOXEL	ZeroThresX,
		const VOXEL	ZeroThresY,
		const VOXEL	ZeroThresZ,
		const VOXEL	ZeroThresT
	)

Set to zero such filter coefficients which are closer to the zero than ZeroThres.

Each axis, if present, is scanned and compared to its threshold.

template<class VOXEL >

void Separable4DFilter< VOXEL >::DisposeData

(

void

)

frees the data arrays [xyzt]Data
