Package inra.ijpb.label.conncomp

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.
