/**
 * @param input - Input mat (Can be MatOfPoint for contours)
 * @return - Difference from perfect score
 */
@Override
public double calculateScore(Mat input) {
    if(!(input instanceof MatOfPoint)) return Double.MAX_VALUE;
    MatOfPoint contour = (MatOfPoint) input;
    double score = Double.MAX_VALUE;

    // Get bounding rect of contour
    Rect rect = Imgproc.boundingRect(contour);
    double x = rect.x;
    double y = rect.y;
    double w = rect.width;
    double h = rect.height;

    double cubeRatio = Math.max(Math.abs(h/w), Math.abs(w/h)); // Get the ratio. We use max in case h and w get swapped??? it happens when u account for rotation
    double ratioDiffrence = Math.abs(cubeRatio - perfectRatio);
