Introduction

This repository is for our ICCV 2023 paper 'Dual Meta-Learning with Longitudinally Generalized Regularization for One-Shot Brain Tissue Segmentation Across the Human Lifespan'.

You can follow the steps below to train your model on your data with DuMeta

1 Preparation

1.1 Install nnUNetv1.

1.2 Process your data as required by nnUNetv1.

1.3 Run nnUNetv1 baseline on your data. Save your Generic_UNet, DataLoader3D, and get_moreDA_augmentation hyperparameters.

1.4 Replace your nnUNet folder with this repository (I rewrote the files in the folders of \nnunet\network_architecture and \nnunet\training\network_training).

1.5 Import Generic_UNet, DataLoader3D, and get_moreDA_augmentation with hyperparameters in step 1.3, as in main.py.

2 Training and Testing

2.1 Meta-train (Pretrain).

python main.py

2.2 Meta-test (Finetune).

Load model parameters of step 2.1, and run baseline as step 1.3.
