There are a few possible further (efficiency optimization) for the 3d segmentation:

  • Parallelize the 3d segmentation over slices if the full amg state is precomputed
  • Parallelize the closing precomputation
  • Refactor the amg state handling so that it can also be used in the standalone 3d segmentation function.

Grep Further optimization to find the locations in the code.

  • Parallelize the operations for postprocessing of instance segmentation with decoder -> make sure to enable passing n_threads so that we avoid oversubscription in case of outer parallelization.

(Not strictly related to the 3d post-processing, but would be very useful for tiling based instance segmentation)
