official code for: Semi-supervised Pathological Image Segmentation via Cross Distillation of Multiple Attentions. MICCAI 2023, early accept arxiv. And the extension is published on the Pattern Recognition 2024.

Overall Framework

There are three branches based on different attention mechanisms and two losses in our framework

usage

First, split the dataset into train, val and test sets, then crop WSIs into patches for computational feasibility.

python utils.move_file.py
python slide_window.py

Then, just use the run.sh script to run the code.

sh run.sh

Data Acquisition

The DigestPath dataset can be downloaded in: DigestPath

The dataset dir is like this after splitting and cropping:

digestpath2019
-----tissue-train-100
-----tissue-train-100-patch
-----tissue-train-5
-----tissue-train-5-patch
-----tissue-val
-----tissue-val-patch
-----tissue-test

You can get data lists in data/digestpath
