Hello everyone,
I have a CT dataset of lower part of human body in DICOM images. I need to separate the femur and tibia bone separately from the dataset. For that obviously i cannot use thresholding because the femur and tibia have same intensities.
So I have used region growing method, ITK confidence connected image filter, but I cannot able to segment the bone.
In what logic i should segment ?

That is a non-trivial problem. Take a look at:

Hello @KSJ,
I believe [TotalSegmentator](https://github.com/wasserth/TotalSegmentator?tab=readme-ov-file) is able to do this. They have an [online tool](https://totalsegmentator.com/) and you can also use it via the [slicer totalsegmentator extension](https://github.com/lassoan/SlicerTotalSegmentator).
