Native Sparse Attention for Optical Remote Sensing Spectral Images

Optical remote sensing (RS) spectral images contain rich cross-band response patterns. Recent RS foundation models (RSFMs) improve compatibility with variable-band inputs through unified or channelwise tokenization, but such input-interface compatibility does not ensure generalization to unseen sensors. Moreover, exist...

GRASP: Granularity-Aware Region Alignment and Semantic Prototype Learning for Fine-Grained Cross-Modal Understanding in Drone Views

The Granularity-Aware Region Alignment and Semantic Prototype (GRASP) learning framework is proposed, enhancing discriminative capability through two synergistic strategies, and Semantic Perturbation Enhanced Matching (SPEM), which leverages a foreground-purified Semantic Prototype Codebook to construct semantically pe...
