2MSPK-Net

This repo is the official implementation of ['2MSPK-Net: A Nuclei Segmentation Network Based on Multi-Scale, Multi-Dimensional Attention, and SAM Prior Knowledge']

<p align="center"> <img src="https://github.com/ThirteenYue/2MSPK-Net/blob/master/prior.png" width="50%" height="50%" /> </p> We proposed a segmentation method based on SAM prior knowledge guidance strategy, and the above is a schematic diagram of integrating SAM prior knowledge.For detailed method introduction, please read the original article

Requirements

Install from the requirements.txt using:

pip install -r requirements.txt

Usage

Note: If you have some problems with the code, the issues may help.

1. Data Preparation

1.1. GlaS and MoNuSeg Datasets

🔥 The original data can be downloaded in following links:

Then prepare the datasets in the following format for easy use of the code:

├── Dataset
    ├── MoNusg
    │   ├── test
    │   │   ├── boundary_priors
    │   │   ├── images
    │   │   ├── masks
    │   │   └── seg_priors
    │   ├── train
    │   │   ├── boundary_priors
    │   │   ├── images
    │   │   ├── masks
    │   │   └── seg_priors	
    │   └── val
    │   │   ├── boundary_priors
    │   │   ├── images
    │   │   ├── masks
            └── seg_priors

2. Training

During the training process, the data were uniformly resized to $256\times256$ pixels and data augmentation was applied, including affine transformation, random flipping, and random rotation. Gradient descent was performed using the Adam optimizer with $\beta_1$ set to 0.9 and $\beta_2$ set to 0.999. The initial learning rate was set to $1\times{10}^{-4}$, and an adaptive learning rate decay strategy was employed. If the loss on the validation set did not decrease after every 20 epochs, the learning rate was reduced by a factor of 0.5. The batch size was set to 4, and the training was completed after 600 epochs.

2.2 Pre-training

We didn't use any pre-trained weights

3. Testing

We also added SAM prior area maps and contour maps to the test data set
