📷 Introduction

rschange is an open-source change detection toolbox, which is dedicated to reproducing and developing advanced methods for change detection of remote sensing images.

• Supported Methods

  BIT (TGRS2021), SNUNet (GRSL2021), ChangeFormer (IGARSS2022),

  LGPNet(TGRS2021), SARAS-Net (AAAI2023), USSFCNet (TGRS2023), AFCF3DNet (TGRS2023)

• Supported Datasets

  • LEVIR-CD
  • DSIFN-CD
  • WHU-CD
  • CLCD
  • SYSU-CD

• Supported Tools

  • Training
  • Testing
  • Params and FLOPs counting

🔥 News

• 2024/07/14: Class activation maps and some other popular methods (BIT, SNUNet, ChangeFormer, LGPNet, SARAS-Net) are now supported.

• 2024/06/24: CDMask has been submitted to Arxiv, see here, and the official implementation of CDMask is available!

🔐 Preparation

• Environment preparation

  conda create -n rscd python=3.9
  conda activate rscd
  conda install pytorch==2.0.0 torchvision==0.15.0 torchaudio==2.0.0 pytorch-cuda=11.7 -c pytorch -c nvidia
  pip install -r requirements.txt

  Note: same as rsseg. If you have already installed the environment of rsseg, use it directly.

• Dataset preprocessing

  LEVIR-CD：The original images are sized at 1024x1024. Following its original division method, we crop these images into non-overlapping patches of 256x256.

  WHU-CD: It contains a pair of dual-time aerial images measuring 32507 × 15354. These images are cropped into patches of 256 × 256 size. The dataset is then randomly divided into three subsets: the training set, the validation set, and the test set, following a ratio of 8:1:1.

  DSIFN-CD & CLCD & SYSU-CD: They all follow the original image size and dataset division method.

  Note: We also provide the pre-processed data, which can be downloaded at this link
