Is there an implementation available for unsupervised 3D segmentation using the Felzenszwalb's Graph Cut algorithm?
If implemented what do you think are the bottlenecks of such an algorithm?
In general, I am looking for a robust unsupervised 3D image segmentation algorithm. I will welcome your suggestions.
