Requirements

pytorch1.7
torchio<=0.18.20
python>=3.6

Notice

You can modify hparam.py to determine whether 2D or 3D segmentation and whether multicategorization is possible.
We provide algorithms for almost all 2D and 3D segmentation.
This repository is compatible with almost all medical data formats(e.g. nii.gz, nii, mhd, nrrd, ...), by modifying fold_arch in hparam.py of the config. I would like you to convert both the source and label images to the same type before using them, where labels are marked with 1, not 255.
If you want to use a multi-category program, please modify the corresponding codes by yourself. I cannot identify your specific categories.
Whether in 2D or 3D, this project is processed using patch. Therefore, images do not have to be strictly the same size. In 2D, however, you should set the patch large enough.

Prepare Your Dataset

Example1

if your source dataset is :

source_dataset
├── source_1.mhd
├── source_1.zraw
├── source_2.mhd
├── source_2.zraw
├── source_3.mhd
├── source_3.zraw
├── source_4.mhd
├── source_4.zraw
└── ...

and your label dataset is :

label_dataset
├── label_1.mhd
├── label_1.zraw
├── label_2.mhd
├── label_2.zraw
├── label_3.mhd
├── label_3.zraw
├── label_4.mhd
├── label_4.zraw
└── ...

then your should modify fold_arch as *.mhd, source_train_dir as source_dataset and label_train_dir as label_dataset in hparam.py

Example2

if your source dataset is :

source_dataset
├── 1
    ├── source_1.mhd
    ├── source_1.zraw
├── 2
    ├── source_2.mhd
    ├── source_2.zraw
├── 3
    ├── source_3.mhd
    ├── source_3.zraw
├── 4
    ├── source_4.mhd
    ├── source_4.zraw
└── ...

and your label dataset is :

label_dataset
├── 1
    ├── label_1.mhd
    ├── label_1.zraw
├── 2
    ├── label_2.mhd
    ├── label_2.zraw
├── 3
    ├── label_3.mhd
    ├── label_3.zraw
├── 4
    ├── label_4.mhd
    ├── label_4.zraw
└── ...

then your should modify fold_arch as */*.mhd, source_train_dir as source_dataset and label_train_dir as label_dataset in hparam.py

Training

without pretrained-model

set hparam.train_or_test to 'train'
python main.py

with pretrained-model

set hparam.train_or_test to 'train'
python main.py -k True

Inference

testing

set hparam.train_or_test to 'test'
python main.py
