Class RegionalExtremaAlgo

java.lang.Object

inra.ijpb.morphology.extrema.RegionalExtremaAlgo

Direct Known Subclasses:

RegionalExtremaByFlooding

public abstract class RegionalExtremaAlgo
extends Object

Interface for appying regional extrema (regional minima and maxima). Example of use:

 ImageProcessor image = IJ.getImage().getProcessor();
 RegionalExtremaAlgo algo = new RegionalExtremaByFlooding(); 
 algo.setConnectivity(4);
 algo.setExtremaType(ExtremaType.MAXIMA);
 ImageProcessor result = algo.applyTo(image);
 ImagePlus resPlus = new ImagePlus("Regional Extrema", result); 
 resPlus.show();
