Function Documentation

template<class VOXEL>

I3D_DLLEXPORT void i3d::Negative

(

Image3d< VOXEL > &

img

)

[inline]

Todo:

Where this function move to? Function necessary to inverse image colors.

template<class VOXELIN, class VOXELOUT>

I3D_DLLEXPORT void i3d::SemiThreshold	(	const Image3d< VOXELIN > &	imgin,
		Image3d< VOXELOUT > &	imgout,
		VOXELIN	t
	)			[inline]

Set intensities of voxels whose intensities are lower or equal to `t` to minimun.

The rest ot htem is left unchanged.

template<class T>

I3D_DLLEXPORT void i3d::Threshold	(	Image3d< T > &	img,
		T	t1,
		T	t2,
		T	lower_value,
		T	upper_value
	)			[inline]

Set intensities of voxels whose intesities are >=t1 and <=t2 to maximum and the others to minimum of the voxel type.

template<class VOXELIN, class VOXELOUT>

I3D_DLLEXPORT void i3d::Threshold	(	const Image3d< VOXELIN > &	imgin,
		Image3d< VOXELOUT > &	imgout,
		VOXELIN	t1,
		VOXELIN	t2
	)			[inline]

Thresholding with creation of a new image, possibly of other voxel type.

template<class T, class OUTVOXEL, class TF>

I3D_DLLEXPORT void i3d::LocalThreshold	(	const Image3d< T > &	,
		Image3d< OUTVOXEL > &	,
		size_t	nx,
		size_t	ny,
		size_t	nz,
		const TF &
	)			[inline]

Perform local thresholding on image in and store its result to binary image out.

The image is devided to nx*ny*nz subregions and a threshold is computed for each such subregion by the threshold finder (see above). An individual threshold for each voxel is computed from the computed thresholds by trilinear interpolation.
