Class RegionalExtremaAlgo

java.lang.Object
inra.ijpb.morphology.extrema.RegionalExtremaAlgo
Direct Known Subclasses:
RegionalExtremaByFlooding
public abstract class RegionalExtremaAlgo
extends java.lang.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();
