UiAs: User-Independent 3D Facial Anti-Spoofing via Multi-modal Wireless Signals
Zhiwei chen, Lebin Lyu, Yimo Zhang +7
Face authentication is widely deployed in security-sensitive applications, while increasingly realistic 3D spoofing attacks pose growing threats. High-fidelity 3D masks can reprodu…
GaMi: Geometry-Agnostic Material Identification via Cross-Modal Subtractive Disentanglement
Zhiwei Chen, Yijie Li, Yimo Zhang +9
Non-contact material identification enables adaptive interaction for embodied intelligence yet faces challenges from geometry-induced variations (e.g., orientation, shape, distance…
A Large Language Model Powered Integrated Circuit Footprint Geometry Understanding
Yida Wang, Taiting Lu, Runze Liu +12
Printed-Circuit-board (PCB) footprint geometry labeling of integrated circuits (IC) is essential in defining the physical interface between components and the PCB layout, requiring…
A Single-Chain Backscatter Tag for Multi-Sensor Multiplexing
Yijie Li, Weichong Ling, Taiting Lu +5
Many real-world sensing tasks require co-located, multi-modal measurements at a single site, typically a bundle of two to five sensors, for example, in plant stress sensing and blo…
