SpikeDiff: Zero-Shot High-Quality Video Reconstruction from Chromatic Spike Camera and Sub-Millisecond Spike Streams

0.5ms) chromatic spike streams. By incorporating physicsbased guidance into the diffusion sampling process, SpikeDiff bridges the domain gap between chromatic spikes and conventional images, enabling high-fidelity reconstruction without requiring domain-specific training data. Extensive experiments demonstrate that SpikeDiff achieves impressive reconstruction quality while maintaining ultra-high temporal resolution, outperforming existing methods across diverse challenging scenarios in both perceptual quality and structural preservation.
