Space-FreqDiffSR: a spatial–frequency coupled diffusion model for high-fidelity super-resolution of remote-sensing images

Shengyu Wang, Qian Shen, Xin Zhang, J J Li et autres

To address the challenge of disentangling spatial-domain structures and frequency-domain spectral characteristics in existing models, we propose Space Frequency Coupled Difference Super-Resolution (Space-FreqDiff SR). The proposed framework adopts a dual-branch collaborative architecture. Specifically, the Spatial Reconstruction Encoding Module (SREM) is designed to …

The DLOD&MCCA Framework for Accurate Mapping of Reservoir Dams in Arid Regions from Remote Sensing Imagery: A Multimodal Fusion and Constraint Approach

Shu Qian, Qian Shen, Majid Gulayozov, Junli Li et autres

Accurate reservoir dam detection in arid regions is challenging because of spectral similarity between dams and surrounding backgrounds, indistinct boundaries, and substantial target-scale variation. To address these issues, this study proposes a deep learning object detection with multi-conditional constraint assistance (DLOD&MCCA) framework …
