totalsegmentator-konfai 1.4.8

Fast and lightweight TotalSegmentator CLI powered by the KonfAI framework.

TotalSegmentator-KonfAI

Fast and lightweight CLI for whole-body CT or MRI segmentation using TotalSegmentator models within the KonfAI framework.

---

🧩 Overview

TotalSegmentator-KonfAI is a lightweight command-line interface (CLI) for running
TotalSegmentator models for multi-organ medical image segmentation,
through the KonfAI deep learning framework.

It provides fast and efficient inference for segmentation tasks, including on low-resource hardware.
Pretrained models are automatically downloaded from
Hugging Face Hub.

🚀 Installation

From PyPI:

python -m pip install totalsegmentator-konfai

From source:

git clone https://github.com/vboussot/KonfAI.git
python -m pip install -e apps/totalsegmentator

---

⚙️ Usage

Perform segmentation on an input volume:

totalsegmentator-konfai total -i path/to/image.nii.gz -o ./Output/

Optional arguments

Flag	Description	Default
TASK	Input modality / model name on Hugging Face	total, total_mr, total_3mm, total_mr_3mm
-i, --input	Path to the input medical image	required
-o, --output	Path to save the segmentation	./Output/
--gt	Path to reference segmentation (ground truth), if available (enables evaluation workflows)	unset
--mask	Path to region-of-interest mask used for evaluation and uncertainty analysis	unset
--gpu	GPU list (e.g. 0 or 0,1)	CPU if unset
--cpu	Number of CPU cores (if no GPU)	1
-q, --quiet	Suppress console output	False

Example

totalsegmentator-konfai total -i path/to/input.nii.gz -o ./Output/ --gt path/to/reference.nii.gz --mask path/to/mask.nii.gz --gpu 0 -uncertainty
