Paper: A Mutual Bootstrapping Model for Automated Skin Lesion Segmentation and Classification. (https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=8990108)

Requirements

Python 3.7
Torch==1.4.0
Torchvision==0.5.0
Apex==0.1
CUDA 10.0

Usage

0. Installation

• Clone this repo

git clone https://github.com/YtongXie/MB-DCNN.git
cd MB-DCNN

1. Data Preparation

• Download ISIC2017 dataset, Extra 1320 images(The ID information of the extra 1320 images is listed in ./dataset/Extra_images.csv)
  

• Put the data under ./dataset/data/

• Run python ./dataset/extractPatch_cls_train.py and python ./dataset/extractPatch_cls_val_test.py to obtain the cropped training, validation and testing patches for classification task.

• Run python ./dataset/extractPatch_seg_train.py to obtain the resized training patches for segmentation task.

• Run python ./dataset/list_cls.py and python ./dataset/list_seg.py to generate the data lists.

2. Training coarse segmentation network (coarse-SN)

• Download pretrained weights from Deeplabv3+, Xception and put them under ./models/ .

• Run python train_CoarseSN.py to train the coarse segmentation network for roughly segmenting skin lesions.

• The segmentation network structure is defined in ./net/models.py, and the hybrid loss is defined in ./net/loss.py.

3. Generating coarse masks

• Run python generate_Coarse_mask.py to obtain the coarse masks for mask-CN and enhanced-SN.

4. Training mask-guided classification network (mask-CN)

• Run python train_MaskCN.py to train the mask-guided classification network for skin lesion classification.

• The classification network structure is defined in ./net/models.py, and the loss is cross-entropy loss.

5. Training enhanced segmentation network (enhanced-SN)

• Run python train_EnhancedSN.py to train the enhanced segmentation network for more accurate skin lesion segmentation.

6. Evaluation

• Run python eval_MaskCN.py and python eval_EnhancedSN.py to start the evaluation.
