metrics results may be wrong

[YChienHung]

In the file metrics.py, meanSen and maxSen is equal, is it a error?

class Medical(object):
    def get_results(self):
        column_Sen = np.mean(self.threshold_Sensitivity, axis=0)
        column_Spe = np.mean(self.threshold_Specificity, axis=0)
        column_Dic = np.mean(self.threshold_Dice, axis=0)
        column_IoU = np.mean(self.threshold_IoU, axis=0)

        return dict(meanSen=column_Sen, meanSpe=column_Spe, meanDice=column_Dic, meanIoU=column_IoU,
                    maxSen=column_Sen, maxSpe=column_Spe, maxDice=column_Dic, maxIoU=column_IoU)
