Spatio-temporal relationship learning methods of ChangeMamba

🗝️Let's Get Started!

`A. Installation`

Note that the code in this repo runs under Linux system. We have not tested whether it works under other OS.

The repo is based on the VMama repo, thus you need to install it first. The following installation sequence is taken from the VMamba repo.

Step 1: Clone the repository:

Clone this repository and navigate to the project directory:

git clone https://github.com/ChenHongruixuan/MambaCD.git
cd MambaCD

Step 2: Environment Setup:

It is recommended to set up a conda environment and installing dependencies via pip. Use the following commands to set up your environment:

Create and activate a new conda environment

conda create -n changemamba
conda activate changemamba

Install dependencies

pip install -r requirements.txt
cd kernels/selective_scan && pip install .

Dependencies for "Detection" and "Segmentation" (optional in VMamba)

pip install mmengine==0.10.1 mmcv==2.1.0 opencv-python-headless ftfy regex
pip install mmdet==3.3.0 mmsegmentation==1.2.2 mmpretrain==1.2.0

`B. Download Pretrained Weight`

Also, please download the pretrained weights of VMamba-Tiny, VMamba-Small, and VMamba-Base and put them under

project_path/MambaCD/pretrained_weight/

`C. Data Preparation`

Binary change detection

The three datasets SYSU, LEVIR-CD+ and WHU-CD are used for binary change detection experiments. Please download them and make them have the following folder/file structure:

${DATASET_ROOT}   # Dataset root directory, for example: /home/username/data/SYSU
├── train
│   ├── T1
│   │   ├──00001.png
│   │   ├──00002.png
│   │   ├──00003.png
│   │   ...
│   │
│   ├── T2
│   │   ├──00001.png
│   │   ... 
│   │
│   └── GT
│       ├──00001.png

│   ├── ...
│   ...
│  
├── train.txt   # Data name list, recording all the names of training data
└── test.txt    # Data name list, recording all the names of testing data

Semantic change detection

The SECOND dataset is used for semantic change detection experiments. Please download it and make it have the following folder/file structure. Note that the land-cover maps are RGB images in the original SECOND dataset for visualization, you need to transform them into single-channel. Also, the binary change maps should be generated by yourself and put them into folder [GT_CD].

Or you are welcome to directly download and use our preprocessed SECOND dataset.

${DATASET_ROOT}   # Dataset root directory, for example: /home/username/data/SECOND
├── train
│   ├── T1
│   │   ├──00001.png

⚗️Results Taken Away

We'd appreciate it if you could give this repo a ⭐️star⭐️ and stay tuned.
Please note that the code we uploaded was reorganised and collated. The models below were also trained using the reorganised code and therefore accuracy may not perfectly match the original paper. In most cases, the accuracy is higher than that in the paper.
We also uploaded prediction results. You can download them and use them directly in your paper [Zenodo] [GDrive][BaiduYun].
