Same as ordfilt2 but for 3D dataset. Can be used as a 3D median , max or min filter. With little modification could be used with any arbitrary function.
for a 3D 100x100x100 uint8 dataset, it runs in about 2.75s on a P4 2.4GHz 1G RAM personnal computer (XP)
% ordfilt3D: Perform 3-D order-statistic filtering on 26 neighbors
% [Vr] = ordfilt3D(V0,ord,padoption)
% use 26 neighbors
% ord = 14 <=> median filtering
% ord = 1 <=> min
% ord = [1 27] <=> [min max]
% padoption: same as in padarray
