UoU: A Universal Fingerprint Foundation Model Based on Large-Scale Unsupervised Learning
Xiongjun Guan, Jianjiang Feng, Jie Zhou
Fingerprint recognition is still dominated by task-specific pipelines, where enhancement, structural parsing, alignment, and matching are optimized in isolation. Although effective…
Cross-Modal Registration Between 3D and 2D Fingerprints via Pose-Aware Unwrapping and Point-Cloud Fusion
Xiongjun Guan, Jianjiang Feng, Jie Zhou
Three-dimensional (3D) fingerprints preserve global finger geometry and local ridge structure while avoiding contact-induced deformation, but they remain difficult to integrate wit…
EgoEMG: A Multimodal Egocentric Dataset with Bilateral EMG and Vision for Hand Pose Estimation
Ziheng Xi, Jiayi Yu, Yitao Wang +3
Surface electromyography (sEMG) records muscle activity during hand movement and can be decoded to recover detailed hand articulation. EMG and egocentric vision are complementary f…
LiCamPose: Combining Multi-View LiDAR and RGB Cameras for Robust Single-timestamp 3D Human Pose Estimation
Zhiyu Pan, Zhicheng Zhong, Wenxuan Guo +3
Several methods have been proposed to estimate 3D human pose from multi-view images, achieving satisfactory performance on public datasets collected under relatively simple conditi…
Fixed-Length Dense Fingerprint Representation with Alignment and Robust Enhancement
Zhiyu Pan, Xiongjun Guan, Yongjie Duan +2
Fixed-length fingerprint representations, which map each fingerprint to a compact and fixed-size feature vector, are computationally efficient and well-suited for large-scale match…
Do MLLMs Understand Pointing? Benchmarking and Enhancing Referential Reasoning in Egocentric Vision
Chentao Li, Zirui Gao, Mingze Gao +3
Egocentric AI agents, such as smart glasses, rely on pointing gestures to resolve referential ambiguities in natural language commands. However, despite advancements in Multimodal…
