Hi! All,<br><br>I tried to use Hessian3DToVesselnessMeasureImageFilter to segment vessel tree in the lung. I have a few questions here<br><br>1. The output Image of Hessian3DToVesselnessMeasureImageFilter is not a binary image as I thought. Can anyone tell me what those voxel value mean? Do I need to <br>
\<br>2. HessianRecursiveGaussianImageFilter's sigma. Anyone know what does this sigma value mean and for? Looks like I can get a biggger vessel by using a bigger sigma?<br><br>3. For thin tube like those vessels in the lung, what's the recommendation value for alph1 and alph2?<br clear="all">
