Modality-Specific Hierarchical Enhancement for RGB-D Camouflaged Object Detection
Yuzhen Niu, Yangqing Wang, Ri Cheng +3
Camouflaged object detection (COD) is challenging due to high target-background similarity, and recent methods address this by complementarily using RGB-D texture and geometry cues…
DocShield: Towards AI Document Safety via Evidence-Grounded Agentic Reasoning
Fanwei Zeng, Changtao Miao, Jing Huang +9
The rapid progress of generative AI has enabled increasingly realistic text-centric image forgeries, posing major challenges to document safety. Existing forensic methods mainly re…
Contrastive Learning for Continuous Touch-Based Authentication
Mengyu Qiao, Yunpeng Zhai, Yang Wang
Smart mobile devices have become indispensable in modern daily life, where sensitive information is frequently processed, stored, and transmitted-posing critical demands for robust…
Towards Generalizable Deepfake Detection with Spatial-Frequency Collaborative Learning and Hierarchical Cross-Modal Fusion
Mengyu Qiao, Runze Tian, Yang Wang
The rapid evolution of deep generative models poses a critical challenge to deepfake detection, as detectors trained on forgery-specific artifacts often suffer significant performa…
