SoftPaint introduces a zero-shot sampling method using soft masks to achieve precise, pixel-level control over diffusion models without requiring expensive annotations or gradient calculations. This approach enables a continuous spectrum of edits for both images and videos, offering a memory-efficient solution that bridges the gap between coarse prompt-based editing and fine-grained re-synthesis.
Diffusion Editing with Soft Mask: Pixel Level Redo of Image and Video with Adjustable Strength
arXiv:2610.00359v1 Announce Type: cross Abstract: Diffusion models with prompt and reference image-guided editing have seen rapid progress, yet they remain too coarse for pixel-level control. One promising direction is to incorporate a soft mask that specifies spatially varying edit strengths but training such fine-grained control demands expensive pixel-wise annotations, while existing zero-shot methods often yield unsatisfactory results. We introduce SoftPaint, a new zero-shot sampling method that leverages soft masks to enable a continuous spectrum of edits, from fully preserving the original content to completely re-synthesizing the masked region. Going beyond zero-shot inpainting methods, we design a Langevin-iteration-based sampler that respects per-pixel soft mask strengths, which applies universally to image and video diffusion models, enabling tasks such as video editing. The method is gradient-free, memory-efficient, and achieves smooth, pixel-level edits across multiple image and video backbones.
