Constructor Detail

ChamferLabelErosion3DShort

public ChamferLabelErosion3DShort(ChamferMask3D mask,
                                  double radius)

Creates a new operator for erosion of label images based on Chamfer masks. The principle is to compute for each non-zero voxel (label), the distance to the nearest background voxel, and to apply a threshold on this distance map.

Parameters:

mask - the Chamfer mask use to propagate distances

radius - the radius used to compute erosion from distance map.

Method Detail

process

public ij.ImageStack process(ij.ImageStack image)

Apply morphological erosion of the labels within the specified input image.

Parameters:

image - the label map to erode

Returns:

the result of erosion.
