Constructor Detail

ChamferLabelDilation3DShort

public ChamferLabelDilation3DShort(ChamferMask3D mask,
                                   double radius)

Creates a new 3D image 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.ImageStack process(ij.ImageStack labelImage)

Computes dilation of labels within label image by a specified radius. Labels can not dilate over existing labels. The function returns a new ImageStack 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.
