Skeletonize BufferedImage with imagej

[Indara]

Hello,

I am trying to skeletonize a bufferedimage with imageJ and save the result of skeleton in buffered image.
I am confuse on how to do it. Can anyone please help me, and give example of the sourcecode.

Thanks

Indara,

Show some working code, and I'll help you fix it.
It's not hard. Just have a look at the API, classes ImagePlus and
ByteProcessor.

This is the code..

        Opener imageOpener = new Opener();
        Image img, imgresult;
        ImagePlus imp = imageOpener.openImage("image.jpg");
        imp.setProcessor(imp.getTitle(),imp.getProcessor().convertToByte(true));
        img = imp.getImage();
        ByteProcessor byteprocessor = new ByteProcessor(img);
        imp.setProcessor(imp.getTitle(),byteprocessor.skeletonize());
        imgresult = imp.getImage();

Please take a look at the code Thanks.

Indara,

As it says here:
 
http://rsb.info.nih.gov/ij/developer/api/ij/process/ByteProcessor.html#skeletonize()

the skeletonize method returns void, not an ImageProcessor.

Also, each ImagePlus has a getProcessor() method, no need to recreate it
every time from the awt.Image generated, in the first place, from that
very same processor.

Thus:


Opener imageOpener = new Opener();
Image img, imgresult;
ImagePlus imp = imageOpener.openImage("image.jpg");
       
imp.setProcessor(imp.getTitle(),imp.getProcessor().convertToByte(true));

ByteProcessor byteprocessor = (ByteProcessor)imp.getProcessor();
byteprocessor.skeletonize();


// the skeletonized image (should be updated)
imgresult = imp.getImage();

// The method above returns you a cached image
// which is usually updated after editing the source processor,
// but not always.
// You can force it to update with:

imp.updateAndDraw();
imgresult = imp.getImage();

// Or just get a new, fresh image directly:
imgresult = byteprocessor.createImage();

Thanks a lot for your suggestion. I will try to implement that.
