Decoupling Defense Strategies for Robust Image Watermarking

CVPR 2026

Deep learning-based image watermarking, while robust against conventional distortions, remains vulnerable to advanced adversarial and regeneration attacks. Conventional countermeasures, which jointly optimize the encoder and decoder via a noise layer, face 2 inevitable challenges:(1) decrease of cle

HiVid: LLM-Guided Video Saliency For Content-Aware VOD And Live Streaming

ICLR 2026poster

Content-aware streaming requires dynamic, chunk-level importance weights to optimize subjective quality of experience (QoE). However, direct human annotation is prohibitively expensive while vision-saliency models generalize poorly. We introduce HiVid, the first framework to leverage Large Language…

MedVR: Annotation-Free Medical Visual Reasoning via Agentic Reinforcement Learning

ICLR 2026poster

Medical Vision-Language Models (VLMs) hold immense promise for complex clinical tasks, but their reasoning capabilities are often constrained by text-only paradigms that fail to ground inferences in visual evidence. This limitation not only curtails performance on tasks requiring fine-grained visual…

Submodel Extraction for Efficient and Personalized Federated Learning via Optimal Transport

CVPR 2026

Federated Learning (FL) enables collaborative model training while preserving data privacy, but its practical deployment is hampered by system and statistical heterogeneity. While federated network pruning offers a path to mitigate these issues, existing methods face a critical dilemma: server-side

Crucible: Quantifying the Potential of Control Algorithms through LLM Agents

NeurIPS 2025poster

Control algorithms in production environments typically require domain experts to tune their parameters and logic for specific scenarios. However, existing research predominantly focuses on algorithmic performance under ideal or default configurations, overlooking the critical aspect of Tuning Poten…
