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…
JDCNet: Confidence-Gated Privileged-Modality Distillation for Cost-Preserving X-ray Inference
Bo Ma, Jinsong Wu, Weiqi Yan +2
We study a systems-level visual inference problem: using an expensive privileged modality during training while preserving a fixed-cost, single-modality deployment path. We present…
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…
Structural Gating and Effect-aligned Lag-resolved Temporal Causal Discovery Framework with Application to Heat-Pollution Extremes
Rui Chen, Jinsong Wu
This study proposes Structural Gating and Effect-aligned Discovery for Temporal Causal Discovery (SGED-TCD), a novel and general framework for lag-resolved causal discovery in comp…
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…
