Method Summary

Modifier and Type	Method and Description
ij.ImageStack	closing(ij.ImageStack image) Performs a morphological closing on the input stack, by applying first a dilation, then an erosion with the reversed structuring element.
ij.ImageStack	dilation(ij.ImageStack image) Implements a default algorithm for dilation, that consists in iterating over the neighbors of each pixel to compute the maximum value.
ij.ImageStack	erosion(ij.ImageStack image) Implements a default algorithm for erosion, that consists in iterating over the neighbors of each pixel to compute the minimum value.
int[][][]	getMask3D() Returns the structuring element as a mask.
int[]	getOffset() Returns the offset in the mask for each direction.
int[][]	getShifts3D() Returns the structuring element as a set of shifts.
int[]	getSize() Returns the size of the structuring element, as an array of size in each direction.
ij.ImageStack	opening(ij.ImageStack image) Performs a morphological opening on the input stack, by applying first an erosion, then a dilation with the reversed structuring element.
Strel3D	reverse() Returns a reversed (i.e.

Constructor Detail

Cross3DStrel

public Cross3DStrel()

Create a new instance of this structuring element.

Method Detail

getSize

public int[] getSize()

Description copied from interface: Strel3D

Returns the size of the structuring element, as an array of size in each direction. The first index corresponds to the number of pixels in the x direction.

Returns:

the size of the structuring element

getMask3D

public int[][][] getMask3D()

Description copied from interface: Strel3D

Returns the structuring element as a mask. Each value is either 0 or 255. The first index corresponds to the z position, the second index to the y direction, and the third one to the x position.

Returns:

the mask of the structuring element

getOffset

public int[] getOffset()

Description copied from interface: Strel3D

Returns the offset in the mask for each direction. The first value corresponds to the shift in the x direction.

Returns:

the offset in the mask

getShifts3D

public int[][] getShifts3D()

Description copied from interface: Strel3D

Returns the structuring element as a set of shifts. The size of the result is N-by-3, where N is the number of elements of the structuring element. The first value corresponds to the shift in the x direction.

Returns:

a set of shifts

reverse

public Strel3D reverse()

Description copied from interface: Strel3D

Returns a reversed (i.e. symmetric wrt the origin) version of this structuring element. Implementations can return more specialized type depending on the implemented interfaces.

Returns:

the reversed structuring element

dilation

public ij.ImageStack dilation(ij.ImageStack image)

Description copied from class: AbstractStrel3D

Implements a default algorithm for dilation, that consists in iterating over the neighbors of each pixel to compute the maximum value. The neighbors are obtained via the getShifts() method.

Specified by:

dilation in interface Strel3D

Overrides:

dilation in class AbstractStrel3D

Parameters:

image - the input image

Returns:

the result of dilation with this structuring element

See Also:

Strel3D.getShifts3D(), AbstractStrel3D.erosion(ImageStack)

erosion

public ij.ImageStack erosion(ij.ImageStack image)

Description copied from class: AbstractStrel3D

Implements a default algorithm for erosion, that consists in iterating over the neighbors of each pixel to compute the minimum value. The neighbors are obtained via the getShifts() method.

Specified by:

erosion in interface Strel3D

Overrides:

erosion in class AbstractStrel3D

Parameters:

image - the input image

Returns:

the result of erosion with this structuring element

See Also:

Strel3D.getShifts3D(), AbstractStrel3D.dilation(ImageStack)

closing

public ij.ImageStack closing(ij.ImageStack image)

Description copied from class: AbstractStrel3D

Performs a morphological closing on the input stack, by applying first a dilation, then an erosion with the reversed structuring element.

Specified by:

closing in interface Strel3D

Overrides:

closing in class AbstractStrel3D

Parameters:

image - the input image

Returns:

the result of closing with this structuring element

opening

public ij.ImageStack opening(ij.ImageStack image)

Description copied from class: AbstractStrel3D

Performs a morphological opening on the input stack, by applying first an erosion, then a dilation with the reversed structuring element.

Specified by:

opening in interface Strel3D

Overrides:

opening in class AbstractStrel3D

Parameters:

image - the input image

Returns:

the result of closing with this structuring element
