DetM-Tracker: Deterministic and Memory-Efficient VIS for Autonomous Industrial Inspection
You-Rui Lin, Jen-Chieh Wu, Tzu-Ti Wei +2
Autonomous industrial inspection requires strictly deterministic real-time inference under tight memory and computational constraints. However, existing Video Instance Segmentation…
AlloEgo-VLM: Disambiguating Allocentric and Egocentric Reference Frames in Vision-Language Models
Kuan-Lin Chen, Tzu-Ti Wei, Chao-Chi Liao +2
This study investigates the challenge of ambiguity faced by Vision-Language Models (VLMs) in understanding spatial semantics. Spatial cognition, shaped by cognitive psychology, spa…
Learning Displacement-Aware WiFi Representations for Weakly Supervised Relative Localization
Tzu-Ti Wei, Po-Cheng Chen, Yu-Chee Tseng +1
WiFi fingerprint-based indoor localization has been widely studied, but most existing approaches focus on absolute positioning and rely on dense coordinate annotations, which are c…
Multi-User Multi-Key Image Steganography with Key Isolation
Tzu-Ti Wei, Yu-Han Tseng, Jun-Yi Lin +2
Steganography conceals secret information within innocuous carriers while preserving visual fidelity and enabling reliable recovery. Recent unified networks operate normally under…
WiFi2Cap: Semantic Action Captioning from Wi-Fi CSI via Limb-Level Semantic Alignment
Tzu-Ti Wei, Chu-Yu Huang, Yu-Chee Tseng +1
Privacy-preserving semantic understanding of human activities is important for indoor sensing, yet existing Wi-Fi CSI-based systems mainly focus on pose estimation or predefined ac…
Resolving Positional Ambiguity in Dialogues by Vision-Language Models for Robot Navigation
Kuan-Lin Chen, Tzu-Ti Wei, Li-Tzu Yeh +3
We consider an autonomous navigation robot that can accept human commands through natural language to provide services in an indoor environment. These natural language commands may…
