SAM-FNet

This repository contains the implementation of the following paper:

SAM-FNet: SAM-Guided Fusion Network for Laryngo-Pharyngeal Tumor Detection

Fine-tune SAM with LoRA

To fine-tune SAM using LoRA, we recommend following the guidelines provided in the original repository: SAMed.

Steps:

1. Fine-tune SAM:
   • Follow the instructions in the SAMed repository to fine-tune SAM with LoRA.
2. Generate Local Images:
   • After fine-tuning, modify the crop_image.py script to suit your requirements.
   • Run the script to generate local images:

python crop_image.py

Dataset

Organize your datasets in the following manner:

datasets/
├── dataset1/
│   ├── global/
│   │   ├── train/
│   │   │   ├── benign/
│   │   │   ├── normal/
│   │   │   └── tumor/
│   │   ├── val/
│   │   │   ├── benign/
│   │   │   ├── normal/
│   │   │   └── tumor/
│   │   └── test/
│   │       ├── benign/
│   │       ├── normal/
│   │       └── tumor/
│   └── local_seg/
│       ├── train/

Training

1. Modify the class_labels variable in the dataset.py file to reflect the classes in your dataset.
2. Run this command to train SAM-FNet.

python train.py --data_dir <Your folder> --save_path <Your output path> --num_classes <Your number of categories for your tasks> --pretrained True --encoder ResNet50

• Replace <Your folder> with the path to your dataset.
• Replace <Your output path> with the directory where you want to save the model checkpoints.
• Replace <Your number of categories for your tasks> with the number of classes in your classification task.

Testing

1. Change "classes" in the val.py
2. Run this command to test.

python val.py --model_path <Your model path> --encoder ResNet50 --dataset <Your dataset name> --save_path <Your output path>

Acknowledgement

The code of SAM-FNet is built upon SAMed and DLGNet, and we express our gratitude to these awesome projects.
