Unsupervised Change Detection for SAR Images Based on Interactive Comparison of Structure Graphs

Graph-based techniques have shown significant potential in the field of unsupervised change detection for synthetic aperture radar (SAR) imagery. Nonetheless, most existing graph-based approaches rely on a single type of basic unit and perform direct comparisons of weight matrices, which limits their ability to represent multi-scale structural variations. In this paper, we introduce an unsupervised method based on interactive comparison of structure graphs (ICSG). This approach employs both regu
