brainchop-models

Pre-trained TensorFlow.js models for brain segmentation, used by NiiVue Desktop.

These models originate from the brainchop project by neuroneural.

Models

Model	Description
brain-extract-full	Full brain extraction (skull stripping)
brain-extract-light	Lightweight brain extraction
parcellation-104	Brain parcellation into 104 regions
parcellation-50	Brain parcellation into 50 regions
tissue-seg-full	Full tissue segmentation (GM/WM/CSF)
tissue-seg-light	Lightweight tissue segmentation

File Structure

Each model directory contains:

• model.json — TensorFlow.js model topology
• model.bin or group1-shard1of1.bin — Model weights
• labels.json — Label definitions for segmentation classes
• settings.json — Model configuration (input shape, preprocessing, etc.)
• preview.png — Preview image of model output
• colormap.json / colormap3.json — Color map for visualization (where applicable)

Usage

These files are downloaded on demand by niivue-desktop during its build process via scripts/download-brainchop-models.js. They are fetched from:
