A plot of a function that displays the change of the W
value dependent on the increase of the noise level (variance σ2) on the input image L
. Additionally representative examples of the results obtained for the same patient for the selected variance (0.001, 0.005, 0.01, 0.02 and 0.05) were shown. Contours K
(n) and K
(n) obtained for the selected level of noise were marked blue and red respectively (analogous to Figure 4).
