Towards Active Cross-View Object Geo-Localization
Shunyu Yao, Xiaohan Zhang, Zhuoran Yang +5
Cross-view object geo-localization (CVOGL) typically assumes a fixed query image, overlooking the ability of mobile agents to actively acquire more informative observations. To add…
DriftingVLA: Native One-Step Vision-Language-Action Generation via Per-Dimension Temporal Drifting
Yuxuan Gao, Shiqi Zhang, Yedong Shen +6
Conventional flow-based vision-language-action (VLA) models support expressive continuous action generation but rely on multi-step refinement to produce each action chunk, increasi…
StreamPPG: Low-Latency rPPG Estimation via Consistent Privileged Learning
Yiming Li, Yihan Yang, Yuguang Chu +7
Remote photoplethysmography (rPPG) estimates the blood volume pulse (BVP) signal from facial videos, enabling contact-free health monitoring. Conventional clip-wise approaches, whi…
SD4R: Sparse-to-Dense Learning for 3D Object Detection with 4D Radar
Xiaokai Bai, Jiahao Cheng, Songkai Wang +5
4D radar measurements offer an affordable and weather-robust solution for 3D perception. However, the inherent sparsity and noise of radar point clouds present significant challeng…
Boosting Instance Awareness via Cross-View Correlation with 4D Radar and Camera for 3D Object Detection
Xiaokai Bai, Lianqing Zheng, Si-Yuan Cao +6
4D millimeter-wave radar has emerged as a promising sensing modality for autonomous driving due to its robustness and affordability. However, its sparse and weak geometric cues mak…
