Method Details

fromDiameter

public static final CuboidStrel fromDiameter(int diam)

Creates a new cube-shape structuring element with the specified diameter (equal to cube side length). All the dimensions of the resulting Cuboid are equal.

Parameters:

diam - the side length of the cube

Returns:

a new 3D cuboid structuring element

fromRadius

public static final CuboidStrel fromRadius(int radius)

Creates a new cube-shape structuring element with the specified radius (such that cube side length equals 2 * radius + 1). All the dimensions of the resulting Cuboid are equal.

Parameters:

radius - the "radius" of the cube

Returns:

a new 3D cuboid structuring element

fromRadiusList

public static final CuboidStrel fromRadiusList(int radiusX,
int radiusY,
int radiusZ)

Creates a 3D structuring element with a cuboid shape and different sizes depending on direction.

Parameters:

radiusX - radius in x direction

radiusY - radius in y direction

radiusZ - radius in z direction

Returns:

a new 3D cuboidal structuring element

fromDiameterList

public static final CuboidStrel fromDiameterList(int diamX,
int diamY,
int diamZ)

Creates a 3D structuring element with a cuboid shape and different sizes depending on direction.

Parameters:

diamX - diameter in x direction

diamY - diameter in y direction

diamZ - diameter in z direction

Returns:

a new 3D cuboidal structuring element

decompose

public java.util.Collection<InPlaceStrel3D> decompose()

Returns a collection of three linear-shape structuring element, along each principal direction.

Returns:

a collection of three in place structuring elements

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

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

reverse

public CuboidStrel reverse()

Returns a cuboidal structuring element with same size, but offset located symmetrically with respect to structuring element center.

Returns:

the reversed version of this strel
