LetOccVote: Learning Weakly Supervised 3D Occupancy through Consensus
Chi Zhang, Qi Song, Feifei Li +2
Weakly supervised 3D occupancy prediction reduces the reliance on costly 3D annotations by learning from 2D pseudo-labels generated by vision foundation models. However, existing m…
Ray-Aware Pointer Memory with Adaptive Updates for Streaming 3D Reconstruction
Feifei Li, Qi Song, Chi Zhang +1
Dense 3D reconstruction from continuous image streams requires both accurate geometric aggregation and stable long-term memory management. Recent feed-forward reconstruction framew…
Na-IRSTD: Enhancing Infrared Small Target Detection via Native-Resolution Feature Selection and Fusion
Qian Xu, Chi Zhang, Qiming Zhang +3
Infrared small target detection (IRSTD) faces the inherent challenge of precisely localizing dim targets amid complex background clutter. While progress has been made, existing met…
PoI: A Filter to Extract Pixel of Interest from Novel Views for Scene Coordinate Regression
Feifei Li, Qi Song, Chi Zhang +2
Neural View Synthesis (NVS) techniques such as NeRF and 3D Gaussian Splatting (3DGS) have enabled photorealistic rendering from novel viewpoints and are increasingly used to augmen…
Improving Hierarchical Representations of Vectorized HD Maps with Perspective Clues
Chi Zhang, Qi Song, Feifei Li +2
The construction of vectorized High-Definition (HD) maps from onboard surround-view cameras has become a significant focus in autonomous driving. However, current map vector estima…
