Freq-LoRA: Frequency-Domain Low-Rank Adaptation for Weather-Robust Aircraft Segmentation in EO Remote Sensing

Adverse weather poses a major challenge to ground-based electro-optical (EO) aircraft surveillance. Existing parameter-efficient fine-tuning (PEFT) methods operate mainly in the spatial domain and treat weather as a generic domain shift rather than a frequency-dependent degradation. We propose Freq-LoRA, a frequency-do...

GeoAdapt: Fine-Grained Keypoint Localization via Deformable Feature Refinement for Ground-Based Optical Remote Sensing

GeoAdapt is introduced, a compact keypoint detection framework that inserts deformable convolution v2 (DCNv2) modules between the feature pyramid network (FPN) neck and the detection head and replaces the standard object keypoint similarity (OKS) loss with a combination of Wing Loss and Bone Loss.

Learning Structural Illumination for Unsupervised Low-light Enhancement

A Relative Illumination Structure Estimation (RISE) framework is proposed that decouples relative illumination structure from absolute exposure and infers it from reliable bright regions, enabling interpretable and robust enhancement.
