Hello Prabhu,

It seems  that you might be oversmoothing your images during the groom (image preprocessing) stage. Perhaps your Gaussian blurring kernel is too high? You can save the images in-between preprocessing steps and reconstruct surfaces using Slicer( slicer->volume rendering) to make sure the distance maps you are generating are correct and meaningful. I would also suggest monitoring the number of anti-aliasing iterations, to make sure its not oversmoothing the image boundaries.

best of luck!

regards,

Rabia

Using the Studio module, one of the main problems I seem to be encountering is with the gaussian smoothing. Without it, the models are bad (very jagged ends), which is not very useful. With a sigma that causes surface smoothness, the attached image is the result. How can this be mitigated?

Hi, 

I'm trying to find the shape models for Vertebra. I'm utterly failing in finding them and I think that might be because of the parameters that I haven't appropriately set. 

Can you please help me with this?

The segmentations are available here.
