Usage

Dataset

In this paper, we perform the experiments using three imaging modalities, including the polyp images, fundus images, and prostate MR images. They could be downloaded from the public websites, or copied from FedDG and PraNet.

Pre-processing

After downloading the data resources, please run the file utils/prepare_dataset.py. Note that the file directory should be replaced with yours.

Training

Run the train script $ python scripts/train_lcfed.py.

Testing

Please download the pre-trained weights from Baidu Disk (https://pan.baidu.com/s/10HkQ90xeFcHMaNgfIyT0iw, a1sm) and put them in the project directory.

Rename the directory as logs/{dataset}/{exp_name}/model/.

Run the test script $ python scripts/test.py.

Result

The test IoU scores and ASSD scores on the Polyp dataset are:
