In recent years, advancements in deep learning for computer vision (CV) have transformed RSCD, significantly enhancing its effectiveness. However, existing methods often overlook the importance of depth information, focusing primarily on 2-D information. This limits their ability to capture subtle changes and structural details in 3-D space. To address these limitations, we introduce ChangeDA—a depth-augmented multitask network designed to enhance the effectiveness of RSCD. ChangeDA introduces a depth encoder module to extract implicit depth information from optical images, enabling the utilization of 3-D structural information without reliance on external data sources. Through the depth infusion module (DIM), depth information is integrated into the dual-temporal feature maps, significantly enhancing the network’s ability to perceive changes in 3-D spatial structures. In addition, ChangeDA includes a differential feature extractor (DFE) tailored to pinpoint differential features between sequential images, and an adaptive all-feature fusion (AAFF) strategy that significantly improves recognition accuracy and generalization capability through cross-level feature integration. Performance evaluations on four prominent single-modal datasets—LEVIR-CD, S2Looking, WHU-CD, and SYSU-CD—yielded state-of-the-art (SOTA) <i>F</i>1 -scores of 92.27%, 66.42%, 94.12%, and 82.74%, respectively. Furthermore, ChangeDA also achieved outstanding results on the multimodal 3DCD dataset, with an <i>F</i>1 score of 63.52% in 2-D CD and an RMSE of 1.20 in the 3-D CD task. These results demonstrate ChangeDA’s robust adaptability across diverse targets and real-world scenarios.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"ChangeDA: Depth-augmented multitask network for remote sensing change detection via differential analysis","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-07-02 01:32:01.575551","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2025,"MonPub":null,"DateUpdate":"2025-07-07","DateCreate":"2025-07-07","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0,"DOI":"10.1109/tgrs.2025.3532468"},"refs":null,"anarec":{"AnaID":409680,"PubliDate":2025,"Pagination":"1-19","XtraPublOfAnaID":null,"ISBN":null,"Volume":"63","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43132,"SerRR":"IEEE transactions on geoscience and remote sensing.
