Towards Quantum Range Query for Spatial-Temporal-Semantic Trajectory Data
Hao Li, Zhihang Liu, Liwei Zou +2
Range query is a fundamental task in geospatial data search and many other downstream applications. Classic range queries often rely on tree-based spatial indexes, of which the que…
-Bridge: A Look-Parametric Diffusion Bridge
Xuran Hu, Yujie Zhu, Tengxi Wang +2
Multiplicative Gamma noise is a signal-dependent degradation in coherent imaging; synthetic aperture radar (SAR) despeckling is its most prominent real-world instance. Existing dif…
Smart Transfer: Leveraging Vision Foundation Model for Rapid Building Damage Mapping with Post-Earthquake VHR Imagery
Hao Li, Liwei Zou, Wenping Yin +4
Living in a changing climate, human society now faces more frequent and severe natural disasters than ever before. As a consequence, rapid disaster response during the "Golden 72 H…
GeoHeight-Bench: Towards Height-Aware Multimodal Reasoning in Remote Sensing
Xuran Hu, Zhitong Xiong, Zhongcheng Hong +3
Current Large Multimodal Models (LMMs) in Earth observation are predominantly evaluated on planar optical tasks and often neglect the vertical dimension, although vertical geometri…
