Frequency-Forcing: Guiding Image Generation via Soft Auxiliary Streams
A new approach to flow-matching models uses lightweight learnable wavelets to guide pixel generation toward coarse structure first, improving image synthesis without hard constraints.
Frequency-Forcing guides image generation through soft auxiliary low-frequency streams instead of hard frequency constraints, improving synthesis quality.
- — Flow-matching models benefit from generating coarse structure before fine detail, mimicking natural image formation.
- — K-Flow enforces frequency ordering by reinterpreting frequency scaling as time; Latent Forcing uses semantic auxiliary flows.
- — Frequency-Forcing combines both paradigms: soft guidance via an auxiliary low-frequency stream that matures earlier.
- — Self-forcing signal derives from learnable wavelet packet transforms applied to data, avoiding external pretrained encoders.
- — On ImageNet-256, method outperforms pixel and latent-space baselines; composes with semantic streams for further gains.
- — Forcing-based ordering preserves the core flow coordinate system, offering modularity over hard constraint rewrites.
Frequently asked
- K-Flow imposes a hard frequency constraint by reinterpreting frequency scaling as flow time and operating in transformed amplitude space. Frequency-Forcing achieves the same frequency-ordered generation through soft guidance: an auxiliary low-frequency stream matures earlier and guides the main pixel flow without rewriting the core flow coordinate system. This makes Frequency-Forcing more modular and composable.
