Can Vision-Language Models Think from the Sky? Unifying UAV Reasoning and Generation
Jintao Sun, Gangyi Ding, Donglin Di +2
Vision-Language Models have achieved strong progress in ground-view visual understanding, yet they remain brittle in high-altitude Unmanned Aerial Vehicle scenes, where objects are…
Harnessing Weak Pair Uncertainty for Text-based Person Search
Jintao Sun, Zhedong Zheng, Gangyi Ding
In this paper, we study the text-based person search, which is to retrieve the person of interest via natural language description. Prevailing methods usually focus on the strict o…
Uncertainty-Aware Trajectory Prediction: A Unified Framework Harnessing Positional and Semantic Uncertainties
Jintao Sun, Hu Zhang, Gangyi Ding +1
Trajectory prediction seeks to forecast the future motion of dynamic entities, such as vehicles and pedestrians, given a temporal horizon of historical movement data and environmen…
Echo Planning for Autonomous Driving: From Current Observations to Future Trajectories and Back
Jintao Sun, Hu Zhang, Gangyi Ding +1
Modern end-to-end autonomous driving systems suffer from a critical limitation: their planners lack mechanisms to enforce temporal consistency between predicted trajectories and ev…
From Data Deluge to Data Curation: A Filtering-WoRA Paradigm for Efficient Text-based Person Search
Jintao Sun, Hao Fei, Zhedong Zheng +1
In text-based person search endeavors, data generation has emerged as a prevailing practice, addressing concerns over privacy preservation and the arduous task of manual annotation…
