SeaNet

This project provides the code and results for 'Lightweight Salient Object Detection in Optical Remote-Sensing Images via Semantic Matching and Edge Alignment', IEEE TGRS, 2023. IEEE link and arxiv link Homepage

Network Architecture

Requirements

python 3.7 + pytorch 1.9.0

Saliency maps

We provide saliency maps of our SeaNet on ORSSD, EORSSD, and additional ORSI-4199 datasets in './models/saliency_maps.zip'.

Training

We use data_aug.m for data augmentation.

Modify paths of datasets, then run train_SeaNet.py.

Note: our main model is under './model/SeaNet_models.py'

Pre-trained model and testing

1. We provide the pre-trained models in './models/'.

2. Modify paths of pre-trained models and datasets.

3. Run test_SeaNet.py.

Evaluation Tool

You can use the evaluation tool (MATLAB version) to evaluate the above saliency maps.
