I used images from "test_images.zip" to create a 'image recognition' neural network file type. When I select the color mode to 'Black and White' and hit the next button I get a NullPointerException. If I select color mode 'color' then I do not get NullPointerException even though these images appear to be black and white.

    The fix will be avialable in next release very soon.

    In FractionRGBData class:

    public static double[] convertRgbInputToBinaryBlackAndWhite(double[] inputRGB) {
    double inputBinary[]= new double[inputRGB.length/3];

    for(int i=0; i<inputRGB.length; i+=3) {
    if (inputRGB[i]>0) {
    inputBinary[i/3] = 0;
    } else {
    inputBinary[i/3] = 1;
    }
    }

    return inputBinary;
    }

    And in ImageRecognitionHelper

    public static DataSet createBlackAndWhiteTrainingSet(List<String> imageLabels, Map<String, FractionRgbData> rgbDataMap) throws VectorSizeMismatchException
    {
    int inputCount = rgbDataMap.values().iterator().next().getFlattenedRgbValues().length / 3;
    int outputCount = imageLabels.size();
    DataSet trainingSet = new DataSet(inputCount, outputCount);

        for \(Entry&lt;String, FractionRgbData&gt; entry : rgbDataMap.entrySet\(\)\) \{
        double\[\] inputRGB = entry.getValue\(\).getFlattenedRgbValues\(\);

    double[] inputBW = FractionRgbData.convertRgbInputToBinaryBlackAndWhite(inputRGB);
    double[] response = createResponse(entry.getKey(), imageLabels);
    trainingSet.addRow(new DataSetRow(inputBW, response));
    }

    return trainingSet;
    }

    I wish to express appreciation to you for bailing me out of this crisis. After looking throughout the the web and obtaining concepts that were not powerful, I was thinking my life was gone. Living without the strategies to the difficulties youve fixed through your entire report is a critical case, as well as ones which might have in a wrong way damaged my career if I had not come across the blog. Your primary talents and kindness in maneuvering all the details was vital. Im not sure what I would have done if I had not come across such a solution like this. Its possible to at this time look ahead to my future. Thanks for your time so much for your specialized and result oriented guide. I will not hesitate to recommend your web sites to anyone who needs guidance about this area.
