Cooccurrence Matrix about imagej-ops

More Information: The affected branch is firstorderstatistics.

I have used the Matlab Image Processing Toolbox function graycomatrix to create the Cooccurence Matrix. To reproduce this here is the Matlab Code to create the Cooccurence Matrix.

    imggrey = imread('path_to_file');
    glcm = graycomatrix(imggrey, 'NumLevels', 32, 'Offset', [-1 1], 'Symmetric', true)

To get the Cooccurence Matrix in Java.

    final HaralickDescriptorSet<IterableInterval> desc = new HaralickDescriptorSet<IterableInterval>(
        context, IterableInterval.class);

    final Img<UnsignedByteType> img = (Img<UnsignedByteType>) new ImgOpener().openImg(
        "path_to_file").getImg();

    desc.compile();
    desc.update(img);

    desc.updateParameterNrGrayLevels(32);
    desc.updateParameterDistance(1);
    desc.updateParameterOrientation(MatrixOrientation.DIAGONAL);

    for (final Pair<String, DoubleType> res : desc) {
        System.out.println(res.getA() + " " + res.getB().get());
    }

@DanielSeebacher could you also post the different outputs? Maybe I can guess from those what is happening...

@dscho Of course, you can see the results in the attached .csv files.

I think I found the bug and fixed it. @DanielSeebacher can you check, confirm and close the issue?

[dietzc]

fixed!
