Open-CD is an open source change detection toolbox based on a series of open source general vision task tools.

• 4/21/2023 - Open-CD v1.0.0 is released in 1.x branch, based on OpenMMLab 2.0 ! PyTorch 2.0 is also supported ! Enjoy it !
• 3/14/2023 - Open-CD is upgraded to v0.0.3. Semantic Change Detection (SCD) is supported !
• 11/17/2022 - Open-CD is upgraded to v0.0.2, requiring a higher version of the MMSegmentation dependency.
• 9/28/2022 - The code, pre-trained models and logs of ChangerEx are available. 😋
• 9/20/2022 - Our paper Changer: Feature Interaction is What You Need for Change Detection is available!
• 7/30/2022 - Open-CD is publicly available!
