Method Detail

fromRadius

public static final BallStrel fromRadius(double radius)

Creates a structuring element with a spherical shape of the given radius.

Parameters:

radius - the radius of the structuring element, in pixels

Returns:

a new structuring element with ball shape and specified radius

fromDiameter

public static final BallStrel fromDiameter(double diam)

Creates a structuring element with a spherical shape of the given diameter.

Parameters:

diam - the diameter of the ball, in pixels

Returns:

a new structuring element with ball shape and specified radius

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)

Performs dilation with a ball structuring element by calling the ImageJ Filters3D.filter method, using Filters3D.MAX option.

Specified by:

dilation in interface Strel3D

Overrides:

dilation in class AbstractStrel3D

Parameters:

image - the 3D stack to process

Returns:

the result of dilation with this structuring element

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

erosion

public ij.ImageStack erosion(ij.ImageStack image)

Performs erosion with a ball structuring element by calling the ImageJ Filters3D.filter method, using Filters3D.MIN option.

Specified by:

erosion in interface Strel3D

Overrides:

erosion in class AbstractStrel3D

Parameters:

image - the 3D stack to process

Returns:

the result of erosion with this structuring element
