Usage

From source file:utils.PreProcessing.java

public BufferedImage enhance(BufferedImage img) {
    Utils ut = new Utils();

    ut.Img2GrayScale(img);//from   w w w  .  j a v  a 2s  . com
    Mat source = ut.bufferedImageToMat(img);

    Mat destination = new Mat(source.rows(), source.cols(), source.type());

    //Melhora constraste
    //Imgproc.equalizeHist(source, destination);
    //Melhora brilho
    source.convertTo(destination, -1, 2, 60);

    //Suavizao
    // Imgproc.GaussianBlur(source, destination, new Size(11, 11), 0);

    //Melhora a definio
    Imgproc.GaussianBlur(source, destination, new Size(0, 0), 10);
    Core.addWeighted(source, 1.8, destination, -0.8, 0, destination);
    //return ut.convertMatToImage(destination);
    BufferedImage imgRetorno = ut.matToBufferedImage(destination);
    return imgRetorno;
