Function Documentation

VImage VErodeImage3d	(	VImage	src,
		VImage	dest,
		VoxelList	se,
		int	nse
	)

3D morphological erosion

Parameters:

	src	input image (bit repn)
	dest	output image (bit repn)
	se	structuring element
	nse	number of elements in the structuring element

Performs a 3D binary morphological erosion using Minkowski addition. The structuring element must be given as an array of voxel- addresses, i.e. as SEstruct *list, together with the length of that list. A binary raster image can be converted into this structure by calling the function "ConvertSE".

VImage VDilateImage3d	(	VImage	src,
		VImage	dest,
		VoxelList	se,
		int	nse
	)

3D morphological dilation

Parameters:

	src	input image (bit repn)
	dest	output image (bit repn)
	se	structuring element
	nse	number of elements in the structuring element

Performs a 3D binary morphological dilation using Minkowski addition. The structuring element must be given as an array of voxel- addresses, i.e. as SEstruct *list, together with the length of that list. A binary raster image can be converted into this structure by calling the function "ConvertSE".

VoxelList VConvertSE3d	(	VImage	src,
		int *	nse
	)

convert a structuring element given as a raster image into a voxel list. The voxel list representation is more efficient computationally.

Parameters:

	src	input image (bit repn)
	*nse	ptr to the number of elements in the voxel list.

This function generates a structuring element that can be used as input into VDilateImage3d or VErodeImage3d.

VImage VGenSphere3d

(

VShort

radius

)

generate a sphere shaped object. The output can be used as a structuring element (after passing it through VConvertSE3d).

Parameters:

radius

gives the radius of the SE

VImage VGenSphere2d

(

VShort

radius

)

generate a sphere shaped object, only the center slice is filled with foreground voxels. The output can be used as a structuring element (after passing it through VConvertSE3d).

Parameters:

radius

gives the radius of the SE
