[Insight-users] histogram based median filter

[Matthias Ebert]

Hi everybody,

is there any histogram based median filter implementation in itk?
I am using a median filter with a kernel radius of 15 on a 384x384 px 
grayscale image and it takes about 30 seconds. Same picture with a 
radius of 2 takes about 0.8 seconds.
Now i have read this article: http://nomis80.org/ctmf.pdf and figured 
out that there is a way to implement median filtering with constant time.

Due to the fact that median filtering is a very basic operation i wonder 
if there is any aproach in itk with histogram based methods?

Thanks

Matthias
