[Insight-users] Time Performance of the ConfidenceConnected filter

Dear all:
I'm using itkConfidenceConnectedImageFilter to automatically extract a
tube-like shape that represents about 10% of a 512*512*256 dataset.
My program runs on a Linux Core 2 Duo machine with 4 Gb Ram mem. I need
about 7 minutes to segment my dataset.
Although thanks to ITK my segmentation is successful, I think the time
needed to segment my dataset is relatively high. Thus, I was wondering
whether I did something wrong or if such filter is known to have a poor
time-efficiency. Is there any alternatives or pre-processing that could
accelerate this segmentation process?
In addition, I'm using the signedmaurerDT and I realized that I had weird
results if I do not template my output image over a REAL type. Is it a
normal behavior?
Thanks for your help and comments.
Flo.
