A Dual-Mode Hydraulic Actuator for a Quasi-Passive Load-Carrying Exoskeleton in Multiple Conditions

RA-L 2026

Lower limb exoskeleton robots have been widely researched for load-carrying assistance. Recently, quasi-passive exoskeletons using low-power elements to modulate mechanical characteristics have emerged. However, achieving effective damping and stiffness across varying tasks and loads remains challen

Dynamic Collaboration of Multi-Language Models based on Minimal Complete Semantic Units

EMNLP 2025

This paper investigates the enhancement of reasoning capabilities in language models through token-level multi-model collaboration. Our approach selects the optimal tokens from the next token distributions provided by multiple models to perform autoregressive reasoning. Contrary to the assumption th

Domain Generalization via Shuffled Style Assembly for Face Anti-Spoofing

CVPR 2022poster

With diverse presentation attacks emerging continually, generalizable face anti-spoofing (FAS) has drawn growing attention. Most existing methods implement domain generalization (DG) on the complete representations. However, different image statistics may have unique properties for the FAS tasks. In…

Auto-Fas: Searching Lightweight Networks for Face Anti-Spoofing

ICASSP 2020accepted

With the development of mobile devices, it is hopeful and pressing to deploy face recognition and face anti-spoofing (FAS) model on cell phone or portable devices. Most of existing face anti-spoofing methods focus on building computational costly detector for better spoofing face detection performan…

Deep Spatial Gradient and Temporal Depth Learning for Face Anti-Spoofing

CVPR 2020oral

Face anti-spoofing is critical to the security of face recognition systems. Depth supervised learning has been proven as one of the most effective methods for face anti-spoofing. Despite the great success, most previous works still formulate the problem as a single-frame multi-task one by simply aug…

Searching Central Difference Convolutional Networks for Face Anti-Spoofing

CVPR 2020poster

Face anti-spoofing (FAS) plays a vital role in face recognition systems. Most state-of-the-art FAS methods 1) rely on stacked convolutions and expert-designed network, which is weak in describing detailed fine-grained information and easily being ineffective when the environment varies (e.g., differ…

A Dataset and Benchmark for Large-Scale Multi-Modal Face Anti-Spoofing

CVPR 2019poster

Face anti-spoofing is essential to prevent face recognition systems from a security breach. Much of the progresses have been made by the availability of face anti-spoofing benchmark datasets in recent years. However, existing face anti-spoofing benchmarks have limited number of subjects (<=170) and…
