thank you, the code above works fine. Then how to calculate contrast, correlation, homogeneity? how do you get the value

My code just arrived at matrix normalization, how to calculate the value of glcm features such as entropy, energy, contrast, correlation, and homogeneity. Here is the code

private void Classification() {

    Mat gl = Mat.zeros(256, 256, CvType.CV_64F);
    Mat glt = gl.clone();

    //Create GLCM d= 1 , angle = 0
    for (int y = 0; y < finalResult.rows(); y++) {
        for (int x = 0; x < finalResult.cols()-1; x++) {

            int i = (int) finalResult.get(y, x)[0];
            int j = (int) finalResult.get(y, x + 1)[0];

            double[] count = gl.get(i, j);
            count[0]++;
            gl.put(i, j, count);
        }
    }

    //GLCM Transpose
    Core.transpose(gl, glt);

    //Symmetric Matrix
    Core.add(gl, glt, gl);

    //Matrix Normalization
    Scalar sum = Core.sumElems(gl);
    Core.divide(gl, sum, gl);

Sorry before, the above code still occurs error. The error is "Cannot resolve metode sum"
