Hello Imagers,
I need help with this: I need to use the plugins of imageJ in my
application  with the command for Make binary:

*IJ.runPlugin(imp,"ij.plugin.Thresholder", "Make Binary");*

And skeletize it...
*IJ.runPlugIn(imp,"ij.plugin.filter.Binary", "Skeletonize");    *

But the image I get appears noised all times,may be I am missing some
parameter?

I am copying here the classes I am writting ..
If someone can help me I will send the image of the check to personal mail
because this list does not accept attached files ...

Thank you very much if someone may help me..

*Class for the preprocessing:*

package com;
import ij.IJ;
import ij.ImagePlus;
import java.awt.image.BufferedImage;

public class Preprocessing {

    //  Binarizacion...
   public BufferedImage umbralizarFirma(BufferedImage firma) {
        ImagePlus imp;
        imp = new ImagePlus("firmaOriginal", firma);
        IJ.runPlugIn(imp,"ij.plugin.filter.Binary", "Make Binary");
        BufferedImage bf = (BufferedImage) imp.getImage();
        return bf;
    }
    //  Skeletonize...
    public BufferedImage skeletonFirma(BufferedImage firma) {
        ImagePlus imp;
        imp = new ImagePlus("firmaOriginal", firma);
        IJ.runPlugIn(imp,"ij.plugin.filter.Binary", "Skeletonize");
        BufferedImage bf = (BufferedImage) imp.getImage();
        return bf;
    }
}
