[ITK] [ITK-users] Whole body Segmentation-Identification

[Nicolas Gallego]

Hi Bumpy,
It seams that your problem is exploratory and will get benefit of manual
interaction. Have you tried visualizing your images in ITKSnap for example?
There are tools to do manual segmentation there.
Hope that helps

>    2. Use 'ImageReadRegionOfInterestWrite.cxx' for separating various
>    parts (like left lung, right lung, spines, head etc.) and save them in
>    respective 3D volumes in mhd format.
>    3. Pick the various body parts prepared above, one by one and segment
>    them using robust algorithm (say
>    ThresholdSegmentationLevelSetImageFilter.cxx).
>    4. Use Mathematical Morphology to get better results.
>    5. Using the various results from above, form an algorithm for
>    identifying the various body parts.

> start[0] = 255;
> start[1] =165;
> start[2] = 0;
