TransUNet

This repo holds code for TransUNet: Transformers Make Strong Encoders for Medical Image Segmentation

Usage

1. Download Google pre-trained ViT models

• Get models in this link: R50-ViT-B_16, ViT-B_16, ViT-L_16...

wget https://storage.googleapis.com/vit_models/imagenet21k/{MODEL_NAME}.npz &&
mkdir ../model/vit_checkpoint/imagenet21k &&
mv {MODEL_NAME}.npz ../model/vit_checkpoint/imagenet21k/{MODEL_NAME}.npz

2. Prepare data

Please go to "./datasets/README.md" for details, or please send an Email to jienengchen01 AT gmail.com to request the preprocessed data. If you would like to use the preprocessed data, please use it for research purposes and do not redistribute it.

3. Environment

Please prepare an environment with python=3.7, and then use the command "pip install -r requirements.txt" for the dependencies.

4. Train/Test

• Run the train script on synapse dataset. The batch size can be reduced to 12 or 6 to save memory, and both can reach similar performance.

CUDA_VISIBLE_DEVICES=0 python train.py --dataset Synapse --vit_name R50-ViT-B_16

• Run the test script on synapse dataset. It supports testing for both 2D images and 3D volumes.

python test.py --dataset Synapse --vit_name R50-ViT-B_16
