Outline Introduction Vector directional noise detector Vector hybrid filtering Results Conclusions

Introduction Noisy censor or noisy channel noise removal algorithm

Vector directional noise detector ( i, j ) Vector angle function: k=2

Vector hybrid filtering ( i-s, j-t ) θ1 , θ2 , θ3 ,….. θ13 ,…………, θ24 , θ25 k=2 ω1 , ω2 , ω3 ,….. ω13 ,…………, ω24 , ω25

Vector hybrid filtering k=2 = (172, 124, 65) = (156, 107, 51)
