Constructor Detail

LinearDepthStrel3D

public LinearDepthStrel3D(int size)

Creates a new horizontal linear structuring element of a given size.

Parameters:

size - the number of pixels in this structuring element

LinearDepthStrel3D

public LinearDepthStrel3D(int size,
                          int offset)

Creates a new horizontal linear structuring element of a given size and with a given offset.

Parameters:

size - the number of pixels in this structuring element

offset - the position of the reference pixel (between 0 and size-1)

Method Detail

fromDiameter

public static final LinearDepthStrel3D fromDiameter(int diam)

Creates a new line-shape structuring element with the specified diameter (equal to the length of the line).

Parameters:

diam - the length of the line along the Z direction

Returns:

a new linear structuring element

fromRadius

public static final LinearDepthStrel3D fromRadius(int radius)

Creates a new line-shape structuring element with the specified radius (such that orthogonal diameter equals 2*radius+1).

Parameters:

radius - the radius of the line, such that line length equals 2*radius+1

Returns:

a new linear structuring element

inPlaceDilation

public void inPlaceDilation(ij.ImageStack stack)

Description copied from interface: InPlaceStrel3D

Performs dilation of the stack given as argument, and stores the result in the same image.

Parameters:

stack - the input image stack to dilate

inPlaceErosion

public void inPlaceErosion(ij.ImageStack stack)

Description copied from interface: InPlaceStrel3D

Performs erosion of the image given as argument, and stores the result in the same image.

Parameters:

stack - the input image stack to erode

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 LinearDepthStrel3D reverse()

Returns a linear horizontal line with same size and offset equal to size-offset-1.

Returns:

the reversed structuring element
