Roles of olive oil and physical exercise in non-alcoholic fatty liver disease after ultrasound-based evaluation

Figure 1 Ultrasound of different stages of non-alcoholic fatty liver disease accompanied by image noise addition and reduction. A: Gray image of normal liver; B: Gaussian noise on A under gray level; C: Wiener denoise on B; D: Gray image of mild non-alcoholic fatty liver disease (NAFLD); E: Gaussian noise on D under gray level; F: Wiener denoise on E; G: Gray image of moderate NAFLD; H: Gaussian noise on G under gray level; I: Wiener denoise on H; J: Gray image of severe NAFLD; K: Gaussian noise on J under gray level; L: Wiener denoise on K.
