Class FloodFillRegionComponentsLabeling

java.lang.Object

inra.ijpb.algo.AlgoStub

inra.ijpb.label.conncomp.FloodFillRegionComponentsLabeling

All Implemented Interfaces:

Algo

public class FloodFillRegionComponentsLabeling
extends AlgoStub

Computes the labels of the different connected components of a region within a label image. The type of result is controlled by the bitDepth option. Uses a Flood-fill type algorithm. The image pixels are iterated, and each time a foreground pixel not yet associated with a label is encountered, its connected component is associated with a new label.

Method Detail

computeLabels

public ij.process.ImageProcessor computeLabels(ij.process.ImageProcessor image,
                                               int regionLabel)

Computes labels corresponding to connected components of a region within a label map.

Parameters:

image - the label map containing index of each region.

regionLabel - the label of the region whose connected components have to be computed.

Returns:

a new label map with the labels of the connected components of the specified region.
