Constructor Detail

LinearDiagDownStrel

public LinearDiagDownStrel(int size)

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

Parameters:

size - the number of pixels in this structuring element

LinearDiagDownStrel

public LinearDiagDownStrel(int size,
                           int offset)

Creates a new diagonal 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 LinearDiagDownStrel fromDiameter(int diam)

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

Parameters:

diam - the orthogonal diameter of the line

Returns:

a new linear structuring element

fromRadius

public static final LinearDiagDownStrel 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.process.ImageProcessor image)

Description copied from interface: InPlaceStrel

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

Parameters:

image - the input image to dilate

inPlaceErosion

public void inPlaceErosion(ij.process.ImageProcessor image)

Description copied from interface: InPlaceStrel

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

Parameters:

image - the input image to erode

getMask

public int[][] getMask()

Description copied from interface: Strel

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

Returns:

the mask of the structuring element

getOffset

public int[] getOffset()

Description copied from interface: Strel

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

Returns:

the offset in the mask

getShifts

public int[][] getShifts()

Description copied from interface: Strel

Returns the structuring element as a set of shifts. The size of the result is N-by-2, 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: Strel

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 LinearDiagDownStrel reverse()

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

Returns:

the reversed structuring element
