Clone this repository

git clone https://github.com/AngeLouCN/Min_Max_Similarity

Data Preparation

We use five dataset to test its performance:

File structure

|-- data
|   |-- kvasir
|   |   |-- train
|   |   |   |--image
|   |   |   |--mask
|   |   |-- test
|   |   |   |--image
|   |   |   |--mask
|   |-- EndoVis17
|   |   |-- train
|   |   |   |--image
|   |   |   |--mask
|   |   |-- test
|   |   |   |--image
|   |   |   |--mask
......

You can also test on some other public medical image segmentation dataset with above file architecture

Usage

Training: You can change the hyper-parameters like labeled ratio, leanring rate, and e.g. in train_mms.py, and directly run the code.
Testing: You can change the dataset name in test.py and run the code.
