ChangeQuery: Advancing Remote Sensing Change Analysis for Natural and Human-Induced Disasters from Visual Detection to Semantic Understanding
Dongwei Sun, Jing Yao, Kan Wei +6
Rapid situational awareness is critical in post-disaster response. While remote sensing damage assessment is evolving from pixel-level change detection to high-level semantic analy…
Bridging Supervision Gaps: A Unified Framework for Remote Sensing Change Detection
Kaixuan Jiang, Chen Wu, Zhenghui Zhao +3
Change detection (CD) aims to identify surface changes from multi-temporal remote sensing imagery. In real-world scenarios, Pixel-level change labels are expensive to acquire, and…
ChangeBridge: Spatiotemporal Image Generation with Multimodal Controls for Remote Sensing
Zhenghui Zhao, Chen Wu, Xiangyong Cao +5
Spatiotemporal image generation is a highly meaningful task, which can generate future scenes conditioned on given observations. However, existing change generation methods can onl…
Advancing Weakly-Supervised Change Detection in Satellite Images via Adversarial Class Prompting
Zhenghui Zhao, Chen Wu, Di Wang +5
Weakly-Supervised Change Detection (WSCD) aims to distinguish specific object changes (e.g., objects appearing or disappearing) from background variations (e.g., environmental chan…
Plug-and-Play DISep: Separating Dense Instances for Scene-to-Pixel Weakly-Supervised Change Detection in High-Resolution Remote Sensing Images
Zhenghui Zhao, Chen Wu, Lixiang Ru +3
Existing Weakly-Supervised Change Detection (WSCD) methods often encounter the problem of "instance lumping" under scene-level supervision, particularly in scenarios with a dense d…
