DecFlowEdit: Self-Localized Flow-based Image Editing via Guidance Decoupling

Zheyuan Zhan, Can Wang, Jiawei Chen et al. · 2026

Flow-based image editing (FlowEdit) enables inversion-free semantic changes through the difference between source and target velocities. In this paper, we observe that FlowEdit's default classifier-free guidance (CFG) configuration, with asymmetric source and target scales, causes substantial background leakage. Matchi …

Spectral Amplitude Purification in Distribution Matching for Diffusion Distillation

Zhenyu Zhou, Can Wang, Chun Chen et al. · 2026

Distribution Matching Distillation (DMD) enables high-quality diffusion sampling in only a few steps, but its optimization dynamics remain dominated by coarse, low-frequency signals, delaying the recovery of fine-grained details. We identify a pronounced concentration of spectral amplitudes at low frequencies in the DM …
