Two mid-cochlea datasets at the spatial resolution of 12 × 12 × 50 $nm^3$ (dataset-1: 60 × 55 × 42 $μm^3$, dataset-2: 88 × 46 × 60 $μm^3$)

Two training datasets, each consisting of 1536 × 1536 × 100 voxels. (code: trai)

The model was based on the residual 3D U-Net architecture (Lee et al., 2017). The model code can be downloaded by pytorch_connectomics.

python -u main.py --config-base configs/MitoEM/MitoEM-R-Base.yaml --config-file configs/MitoEM/MitoEM-R-BC.yaml

Model parameter: Weight (code: mito)

python -u main.py --config-base configs/MitoEM/MitoEM-R-Base.yaml --config-file configs/MitoEM/MitoEM-R-BC.yaml --inference --checkpoint datasets/output/checkpoint_200000.pth.tar

The volume of mitochondria is the sum of voxels. ANF-associated mitochondria were divided into super voxels with a unit volume of (0.07 $μm^3$) along the longest axis (see code).
