[Insight-users] why use 3D watershed segmentation is very slow?

[Dongfeng Han]

hello everyone,
I use watershed method as shown the example code in ITK, to segment 3D image
with size of 300x300x100
The pixel type is unsigned short.
It's very very slow. may be >20 or 30 min.
Any one know how to make it faster?
May be I set wrong parameters.

best
dongfeng
