Class ChamferLabelDilation2DShort

java.lang.Object

inra.ijpb.algo.AlgoStub

inra.ijpb.label.filter.ChamferLabelDilation2DShort

All Implemented Interfaces:

Algo

public class ChamferLabelDilation2DShort
extends AlgoStub

Apply a dilation by a specified radius to each label of a label map by constraining the dilation. Labels can not dilate over existing labels. Can be applied to label map encoded with 8 or 16 bits integers, or 32 bit floats.

Constructor Detail

ChamferLabelDilation2DShort

public ChamferLabelDilation2DShort(ChamferMask2D mask,
                                   double radius)

Creates a new image processor for dilating labels using the specified chamfer mask, using 16-bits integer computation.

Parameters:

mask - the Chamfer mask to use.

radius - the radius of dilation of labels. In practice, the distance is propagated up to radius + 0.5.

Method Detail

process

public ij.process.ImageProcessor process(ij.process.ImageProcessor labelImage)

Computes dilation of labels within label image by a specified radius. Labels can not dilate over existing labels. The function returns a new ImageProcessor the same size and the same type as the input, with values greater than or equal to zero.

Parameters:

labelImage - the original label map

Returns:

a new label image where each label is dilated over background pixels.
