Paper: https://arxiv.org/abs/2007.00243

News (2021-06-26): Check out our latest work BiX-NAS that is to appear in MICCAI2021! BiX-Net Achieves on par performances to BiO-Net but with 34.9 times fewer parameters and 4.0 times fewer MACs!

Dependencies

• Python >= 3.6
• PIL >= 7.0.0
• matplotlib >= 3.3.1

Keras version

• tensorflow-gpu >= 1.14.0
• keras >= 2.1.5

Pytorch version

• tqdm >= 4.54.1
• imgaug >= 0.4.0
• torch >= 1.5.0
• torchvision >= 0.6.0

NOTE1: Both versions have been sucessfully tested on a GeForce RTX 2080 GPU with CUDA=10.1 and driver=435.21.
NOTE2: You don't need all dependencies to run on a sole backend.

Usage

Use --backend to switch between backends [keras, pytorch], default=keras.

Train

python3 main.py --epochs 300 --iter 3 --integrate --train_data PATH_TO_TRAIN_DATA_ROOT \
		  --valid_data PATH_TO_VALID_DATA_ROOT --exp 1 --backend YOUR_BACKEND

Evaluate

Save metrics and segmentations:

python3 main.py --evaluate_only --save_result --valid_data PATH_TO_VALID_DATA_ROOT --exp 1  --backend YOUR_BACKEND

Print metrics only:

python3 main.py --evaluate_only --valid_data PATH_TO_VALID_DATA_ROOT --exp 1  --backend YOUR_BACKEND

NOTE: --iter,--integrate,--multiplier need to be specidied on the above commands.

or

python3 main.py --evaluate_only --valid_data PATH_TO_VALID_DATA_ROOT --model_path PATH_TO_TRAINED_MODEL  --backend YOUR_BACKEND
