Usage

From source file:ImageProcessing.ImageProcessing.java

public static double[] extractGrayColor(BufferedImage source) {
    //Extracts the gray value from the pixels at the source by 
    //calculating the average of the RGB value at the given pixel.
    int imageWidth = source.getWidth();
    int imageHeight = source.getHeight();
    double[] values = new double[imageWidth * imageHeight];

    for (int i = 0; i < imageHeight; i++) {
        for (int j = 0; j < imageWidth; j++) {
            int rgbValue = source.getRGB(j, i);
            Color currentPixel = new Color(rgbValue, true);
            int value = (currentPixel.getRed() + currentPixel.getGreen() + currentPixel.getBlue()) / 3;
