DSFNet: Dynamic and Static Fusion Network for Moving Object Detection in Satellite Videos

Algorithm Introduction

DSFNet: Dynamic and Static Fusion Network for Moving Object Detection in Satellite Videos, Chao Xiao, Qian Yin, and Xingyi Ying.

We propose a two-stream network named DSFNet to combine the static context information and the dynamic motion cues to detect small moving object in satellite videos. Experiments on videos collected from Jilin-1 satellite and the results have demonstrated the effectiveness and robustness of the proposed DSFNet. For more detailed information, please refer to the paper.

In this code, we also apply SORT to get the tracking results of DSFNet.

Prerequisite

• Tested on Ubuntu 20.04, with Python 3.7, PyTorch 1.7, Torchvision 0.8.1, CUDA 10.2, and 2x NVIDIA 2080Ti.
• You can follow CenterNet to build the conda environment but remember to replace the DCNv2 used here with the used DCNv2 by CenterNet (Because we used the latested version of DCNv2 under PyTorch 1.7).
• You can also follow CenterNet to build the conda environment with Python 3.7, PyTorch 1.7, Torchvision 0.8.1 and run this code.
• The dataset used here is available in [BaiduYun](Sharing code: 4afk). You can download the dataset and put it to the data folder.

Usage

On Ubuntu:

1. Train.

python train.py --model_name DSFNet --gpus 0,1 --lr 1.25e-4 --lr_step 30,45 --num_epochs 55 --batch_size 4 --val_intervals 5  --test_large_size True --datasetname rsdata --data_dir  ./data/RsCarData/

2. Test.

python test.py --model_name DSFNet --gpus 0 --load_model ./checkpoints/DSFNet.pth --test_large_size True --datasetname rsdata --data_dir  ./data/RsCarData/ 

(Optional 1) Test and visulization.

python test.py --model_name DSFNet --gpus 0 --load_model ./checkpoints/DSFNet.pth --test_large_size True --show_results True --datasetname rsdata --data_dir  ./data/RsCarData/ 

(Optional 2) Test and visualize the tracking results of SORT.

python testTrackingSort.py --model_name DSFNet --gpus 0 --load_model ./checkpoints/DSFNet.pth --test_large_size True --save_track_results True --datasetname rsdata --data_dir  ./data/RsCarData/
