Constructor Details

ChamferStrel

public ChamferStrel(ChamferMask2D chamferMask,
double radius)

Creates a new ChamferStrel from a chamfer mask (used for computing distances) and a radius (used to computing the extent of propagation).

Parameters:

chamferMask - the chamfer mask

radius - the radius

Method Details

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

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

reverse

public Strel reverse()

Description copied from interface: Strel

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
