Rapid Strong Earthquake Magnitude Estimation Based on Near-Field High-Rate GNSS Data Using Deep Learning

Guohong Zhang, Chuanchao Huang, Xinjian Shan, Dingwen Zhang, Wenhuan Kuang

Strong earthquakes cause severe casualties and economic losses. Accurate and rapid magnitude estimation can enable timely emergency response and effectively mitigate earthquake disasters. Current mainstream algorithms rely on broadband seismic or strong-motion data, but during st…

IGGT4D: Streaming 4D Instance-Grounded Geometry Transformer

Zhengyu Zou, Hao Li, Kuixuan Jiao, Liu Liu, Tingyang Xiao, Xiaolin Zhou, et al.

Real-world spatial intelligence requires agents to understand scenes from continuous video streams, where objects move, persist, disappear, and reappear over time. While recent spatial foundation models have enabled generalizable feed-forward 3D reconstruction, most streaming met…

UniRef-UAV: A Multimodal Benchmark for Universal Referring in UAV Imagery

Haibin Tian, Huichao Xie, Xuelin Qian, Ruitao Lu, Junwei Han, Dingwen Zhang

Unmanned aerial vehicles (UAVs) increasingly rely on visual grounding capabilities to localize task-relevant targets from diverse instructions in complex aerial scenes. Existing referring expression comprehension (REC) benchmarks and methods, however, are largely built around tex…
