Method Detail

getUnifiedLabels

public static int[] getUnifiedLabels(PrimitiveCatchmentBasinsGraph graph,
                                     Pixel[][] pixels)

Returns a labeling to graph unifying the labels in pixels within each PrimitiveCatchmentBasin.

Parameters:

graph - a PrimitiveCatchmentBasinsGraph to be labeled

pixels - the desired partition in Pixels granularity

Returns:

a labeling for the given graph that most approximates the partition in pixels

getUnifiedLabels

public static int[] getUnifiedLabels(PrimitiveCatchmentBasinsGraph graph,
                                     java.awt.image.BufferedImage desiredPartition)

Returns a labeling to graph unifying the labels in desiredPartitions within each PrimitiveCatchmentBasin.

Parameters:

graph - a PrimitiveCatchmentBasinsGraph to be labeled

desiredPartition - the desired partition in Pixels granularity

Returns:

a labeling for the given graph that most approximates the partition in desiredPartition

fixLabels

public static int[] fixLabels(PrimitiveCatchmentBasinsGraph graph,
                              int[] originalLabels)

Parameters:

originalLabels -

Returns:

a unique label for each ROI (originalLabels may contain same label for distinct ROIs, if a ROI was split by labels unification within PrimitiveCatchmentBasins)
