Research Paper
Core Innovation
This paper introduces Stream-DiffVSR, a causally conditioned diffusion framework that processes only past frames for video super-resolution, combined with a four-step distilled denoiser and Auto-regressive Temporal Guidance. It achieves state-of-the-art perceptual quality with drastically reduced latency, making diffusion-based VSR feasible for online applications.
Why It Matters
Low-latency video super-resolution is critical for live streaming, video conferencing, and real-time broadcasting where delays degrade user experience. Stream-DiffVSR reduces processing delay from thousands of seconds to under half a second, enabling practical deployment of diffusion-based VSR in latency-sensitive environments. This improvement supports scalable workflows in media, entertainment, and communication industries.
