Ziyuan Liu, Ruifei Zhu, Ouqiao Ma, Yuantao Gu
Remote sensing change detection (CD) traditionally focuses on pixel-level binary segmentation, which identifies where changes occur but neither what nor why. To bridge this semantic gap, we introduce JL1-CC&QA, a multi-task benchmark that extends the JL1-CD dataset with two compl…
