The adaptive median filter works in two levels. Lets label them level 1 and level 2. level 1: A1 = n_med - n_min A2 = n_med - n_max If A1 > 0 AND A2 < 0, Goto level 2 Else increase the window size IF window size <= S_max repeat level 1 Else output n_med level 2: B1 = n_xy - n_min B2 = n_xy - n_max If B1 > 0 AND B2 < 0, output n_xy Else output z_med Where, n_min = minimum gray level value in S_xy n_max = maximum gray level value in S_xy n_med = median of gray levels in S_xy n_xy = gray level at coordinates (x,y) S_max = maximum allowed size of S_xy So now go try ....

The adaptive median filter works in two levels. Lets label them level 1 and level 2.

level 1: A1 = n_med - n_min
A2 = n_med - n_max
If A1 > 0 AND A2 < 0, Goto level 2
Else increase the window size
IF window size <= S_max repeat level 1
Else output n_med
level 2: B1 = n_xy - n_min
B2 = n_xy - n_max
If B1 > 0 AND B2 < 0, output n_xy
Else output z_med

Where, n_min = minimum gray level value in S_xy
n_max = maximum gray level value in S_xy
n_med = median of gray levels in S_xy
n_xy = gray level at coordinates (x,y)
S_max = maximum allowed size of S_xy

So now go try ….
