Clean-Reference Streaming Detection of Lens Occlusion and Photometric Transitions for Camera Tamper Monitoring
Bo Ma, WeiQi Yan, Jinsong Wu
The paper presents a lightweight streaming monitor that detects lens occlusion and sudden lighting changes in surveillance cameras by comparing luminance and gradient statistics ag…
COREY: Entropy-Guided Runtime Chunk Scheduling for Selective Scan Kernels
Bo Ma, Jinsong Wu, Weiqi Yan
Mamba selective state space models (SSMs) provide linear-time sequence modeling but remain sensitive to selective-scan chunk scheduling. We present COREY, a \emph{concept-and-feasi…
PPEDCRF: Dynamic-CRF-Guided Selective Perturbation for Background-Based Location Privacy in Video Sequences
Bo Ma, Weiqi Yan, Jinsong Wu
We propose PPEDCRF, a calibrated selective perturbation framework that protects \emph{background-based location privacy} in released video frames against gallery-based retrieval at…
BodhiPromptShield: Pre-Inference Prompt Mediation for Suppressing Privacy Propagation in LLM/VLM Agents
Bo Ma, Jinsong Wu, Weiqi Yan
In LLM/VLM agents, prompt privacy risk propagates beyond a single model call because raw user content can flow into retrieval queries, memory writes, tool calls, and logs. Existing…
PPEDCRF: Privacy-Preserving Enhanced Dynamic CRF for Location-Privacy Protection for Sequence Videos with Minimal Detection Degradation
Bo Ma, Jinsong Wu, Weiqi Yan +2
Dashcam videos collected by autonomous or assisted-driving systems are increasingly shared for safety auditing and model improvement. Even when explicit GPS metadata are removed, a…
Bodhi VLM: Privacy-Alignment Modeling for Hierarchical Visual Representations in Vision Backbones and VLM Encoders via Bottom-Up and Top-Down Feature Search
Bo Ma, Wei Qi Yan, Jinsong Wu
Learning systems that preserve privacy often inject noise into hierarchical visual representations; a central challenge is to \emph{model} how such perturbations align with a decla…
