Class Reconstruction

java.lang.Object
inra.ijpb.morphology.Reconstruction
Direct Known Subclasses:
GeodesicReconstruction
public abstract class Reconstruction
extends java.lang.Object

Morphological reconstruction for grayscale or binary images. Most algorithms works for any data type.

This class provides a collection of static methods for commonly used operations, such as border removal or holes filling.

Example of use: 


 ImageProcessor mask = IJ.getImage().getProcessor();
 ImageProcessor marker = mask.createProcessor(mask.getWidth(), mask.getHeight());
 marker.set(20, 10, 255); 
 ImageProcessor rec = Reconstruction.reconstructByDilation(marker, mask, 4);
 ImagePlus res = new ImagePlus("Reconstruction", rec);
 res.show();

  • Method Summary

    Modifier and Type Method Description
    static ij.process.ImageProcessor fillHoles​(ij.process.ImageProcessor image)
    Fills the holes in the input image, by (1) inverting the image, (2) performing a morphological reconstruction initialized with inverted image boundary and (3) by inverting the result.
    static ij.process.ImageProcessor killBorders​(ij.process.ImageProcessor image)
    Removes the border of the input image, by performing a morphological reconstruction initialized with image boundary.
    static ij.process.ImageProcessor reconstructByDilation​(ij.process.ImageProcessor marker, ij.process.ImageProcessor mask)
    Static method to computes the morphological reconstruction by dilation of the marker image under the mask image.
    static ij.process.ImageProcessor reconstructByDilation​(ij.process.ImageProcessor marker, ij.process.ImageProcessor mask, int connectivity)
    Static method to computes the morphological reconstruction by dilation of the marker image under the mask image.
    static ij.process.ImageProcessor reconstructByErosion​(ij.process.ImageProcessor marker, ij.process.ImageProcessor mask)
    Static method to computes the morphological reconstruction by erosion of the marker image over the mask image.
    static ij.process.ImageProcessor reconstructByErosion​(ij.process.ImageProcessor marker, ij.process.ImageProcessor mask, int connectivity)
