SpecLoR: Spectral Lookahead Rectification for Motion-Coherent Text-to-Video Generation
Researchers have introduced SpecLoR, a novel method to improve the coherence and reduce artifacts in text-to-video generation. This technique addresses issues arising from numerical errors in latent ODE sampling, which often lead to spatiotemporal inconsistencies in generated videos. SpecLoR operates by looking ahead to estimate clean latent states and then rectifying their spectral amplitude in the frequency domain, preserving phase information. This approach effectively bypasses noise and avoids disrupting local geometry, demonstrating significant improvements in motion coherence with minimal computational overhead. AI
