According to Eq. (12), the weight v k, j) between two pixels (x k, y k ) and (x j, y j ) in the original even lighting image f is: vleft k,jright)=frac{exp left -{leftVert {N}_k-{N}_jrightVert}_{2,a}^2/{h}^2right)}{sum left -{leftVert_k^r}{N}_k-{N}_jrightVert {N}_{2{N}_jrightVert}_{sum}^2right)/{h}^2}}.
According to Eq. (11), the estimated value ( overline{Q}left({x}_k,{y}_kright) ) of the pixel (x k, y k ) in the original even lighting image f is computed as: overline{Q}left({x}_k,{y}_kright)=sum limits_{left({x}_j,{y}_jright)in {V}_k^r}vleft k,jright)Qleft({x}_j,{y}_jright).
Similarly, if (g(T s ) + g(P s ))/2 < g(k) ≤ g(P s ), the membership degree of the pixel k in the original even lighting image f according to the S-function in Eq. (14) is mu left(g k)right)=1-2{left(frac{g k -gleft {P}_sright)}{gleft {P}_sright -gleft {T}{gleft {P}_sright -gleft {
If g(T s ) ≤ g(k) ≤ (g(T s ) + g(P s ))/2, the membership degree (the wave transformation value) of the pixel k in the original even lighting image f according to the S-function in Eq. (14) is mu left(g k)right)=2{left(frac{g k -gleft {T}_sright)}{glefrac{g k -gleft {efT}_srightght)}{gleft {P}_sright -gleft {
