Highlight

Novel Segmentation Architectures

Efficient Intra-Layer Multi-scale Subtraction Design

Efficient Inter-Layer Multi-scale Subtraction Structure

Training-free Loss Network

Low FLOPs (comparisons under the Res2Net-50 backbone)

Prerequisites

• Python 3.7
• Pytorch 1.8.1
• OpenCV 4.6
• Numpy 1.19
• Apex

Training/Inference/Testing

• set the cfg in train.py:

    Dataset.Config(datapath='', savepath='', mode='train', batch=16, lr=0.05, momen=0.9, decay=5e-4, epoch='')
    %the number of training epochs settings in the polyp segmentation, COVID-19 Lung Infection, breast tumor segmentation and OCT layer segmentation are 50, 200, 100         and 100, respectively.
    python train.py

• Run prediction_rgb.py (can generate the predicted maps)
• Run test_score.py (support 10 binary segmentation evaluation metrics: MAE, maxF, avgF, wfm, Sm, Em, M_dice, M_iou, Ber, Acc)

TODO LIST

• 3D verison MSNet training.

• Support different backbones (VGGNet, MobileNet, ResNet, Swin, etc.).
