Hi Sergio,<div>Thank you for your advice.</div><div>It seems faster than before.</div><div>Now I segment a liver image with size 300x300x150 , voxel spacing is 0.5x0.5x1.5.</div><div>I set threshold = 0.01 level = 0.1.</div>
<div>The running time is about 5 min and the total number of region is about 37000. </div><div>Is that reasonable? and do you have any suggestion on the parameters and the running time?</div><div>thanks</div><div>Best</div>

<div>Hi there</div><div><br></div>The first check is to make sure you are using a release version of ITK libraries.<div>Debug versions are several times slower (6-10 times in my experience)</div><div>Once this is checked, we can start looking at your parameters.</div>

<div>Any one know how to make it faster? </div><div>May be I set wrong parameters.</div><div><br></div><div>best</div><div>dongfeng</div>
