Package inra.ijpb.morphology

Class MinimaAndMaxima

java.lang.Object
inra.ijpb.morphology.MinimaAndMaxima
public class MinimaAndMaxima
extends java.lang.Object
A collection of static methods for computing regional and extended minima and maxima. Regional extrema algorithms are based on flood-filling-like algorithms, whereas extended extrema and extrema imposition algorithms use geodesic reconstruction algorithm. See the books of Serra and Soille for further details.

Example of use: 


        // Get current image processor
        ImageProcessor image = IJ.getImage().getProcessor();
        // Computes extended minima with a dynamic of 15, using the 4-connectivity
        ImageProcessor minima = MinimaAndMaxima.extendedMinima(image, 15, 4); 
        // Display result in a new imagePlus
        ImagePlus res = new ImagePlus("Minima", minima);
        res.show();
