FD-ProtoSCD: Semantic Change Detection in High-Resolution Remote Sensing Images via Frequency-Domain Disentanglement and Dynamic Prototype Learning

Semantic Change Detection (SCD) in high-resolution remote sensing images is challenged by appearance-induced pseudo-changes and highly imbalanced class transitions. To address these coupled difficulties, we propose FD-ProtoSCD, a decoupled SCD framework that combines Frequency-Domain Change Disentanglement (FDCD) with...

Asymmetric Cross-Modal Hashing With Missing-Modality Feature Compensation for Remote Sensing Image Retrieval

Cross-modal hashing plays a crucial role in large-scale remote sensing (RS) image retrieval. Existing methods often assume that both query and database images are single-modal, each from a different modality. In practice, however, database images are accumulated over a long period and are typically available in multipl...

STAR: Spatio-Temporal Alignment and Refinement for Cross-View Geo-Localization

Cross-view geo-localization (CVGL) aims to match images captured from different viewpoints, such as drone and satellite imagery. Existing methods primarily focus on single-image matching, overlooking the potential of leveraging temporal information from drone image sequences. To address this, we propose Spatio-Temporal...
