Retinal vessel segmentation based on GT-UNet

Introduction

This project is a retinal blood vessel segmentation code based on UNet-like Group Transformer Network (GT-UNet), including data preprocessing, model training and testing, visualization, etc.

Training model

Please confirm the configuration information in the config.py. Pay special attention to the train_data_path_list and test_data_path_list. Then, running:

python train.py

You can configure the training information in config, or modify the configuration parameters using the command line. The training results will be saved to the corresponding directory(save name) in the experiments folder.

3) Testing model

The test process also needs to specify parameters in config.py. You can also modify the parameters through the command line, running:

python test.py  

The above command loads the best_model.pth in ./experiments/GT-UNet_vessel_seg and performs a performance test on the testset, and its test results are saved in the same folder.
