SafeRI: Recognition and Intervention for Token-Level Safety Intervention in Large Vision Language Models

This work proposes a streaming recognition and gated LoRA framework for intrinsic VLM safety, which is trained from unsafe prefixes, transition statements, and safe continuations, so that it learns to redirect unsafe generations back to safe responses after activation.

WorldSculpt: Generating Compositional Worlds from Grounded Videos

This work shows that complex scenes with hundreds of objects can instead be generated compositionally by adapting a strong single-object 3D generative prior to multi-view observations, and introduces UE-MeshyScene, a photorealistic benchmark of densely cluttered scenes with hundreds of objects, per-object annotations,...

Optical Flow from Photons

This work proposes QuantaFlow, the first method for dense optical flow directly from SPAD streams, which embeds SPAD representation construction into iterative flow refinement and constructs multi-scale representations containing intensity and structural cues.

Surprise Forcing: What to Remember, When to Skip in Long Video Generation

This work introduces Surprise Forcing, a training-free framework that treats both limitations as online resource-allocation problems and improves long-horizon consistency and visual quality while retaining real-time streaming throughput.

Bridging Event Streams and DiT: Event-Guided Video Frame Interpolation

This work proposes an adapter-based framework that incorporates event-derived cues into a pre-trained image-to-video diffusion model with minimal architectural changes and consistently outperforms existing state-of-the-art approaches.
