ChronoStitch: Training-Free Composition of Visual KV Memories for Long-Horizon Temporal Reasoning

Santiram Tiwari, Nishant Sinha, Kunal Kislay

Long-video question answering requires a model to preserve visual evidence over time without repeatedly reprocessing the same video. A practical approach is to store the vision-language model's internal key-value (KV) cache for each video chunk and retrieve that state at query ti…

BLUE: Semantics-Preserving Video Compression for Efficient Vision-Language Surveillance Analytics

Shubham Baid, Akash James, Sahil Chachra, Nishant Sinha, Kunal Kislay

Continuous surveillance video creates a growing storage, transmission, and inference burden for enterprise video analytics systems. While modern codecs such as H.265 reduce bitrate for human-viewable video, aggressive compression can degrade downstream computer-vision performance…

BLUE: A Stale-Pixel Optical-Flow Compositor for Entropy-Efficient Surveillance Video Encoding

Shubham Baid, Akash James, Sahil Chachra, Nishant Sinha, Kunal Kislay

Continuous-recording surveillance systems face a storage problem that codec tuning alone cannot fully solve: even at aggressive CRF settings, a static-camera scene spends most of its bits re-encoding a background that has not changed. We present BLUE, a pre-encode compositor that…
