*h*-Edit: Effective and Flexible Diffusion-Based Editing via Doob’s *h*-Transform (CVPR'25)

[Project Page]

Summary

h-Edit is a finetuning-free diffusion-based editing method that frames editing as a reverse-time bridge modeling problem. It leverages Doob’s h-Transform for bridge construction and Langevin Monte Carlo sampling for generating edited samples.

🔥 Key Features

✅ Theoretical Guarantee - Provides both explicit and implicit forms with unique features. Math doesn't lie! 📏
🚀 Training-Free, Simple, General - Smarter edits, zero headaches! 🧠
🏆 Strong Performance, SOTA on PieBench - Tackles tough cases like a champ! 💪
🛠️ Flexible - Supports conditional scores, external reward models; the first to handle both simultaneously! 🎛️
🎯 Compatible - Works with deterministic/random inversion, P2P, MasaCtrl and Plug-n-Play or even without attention control! 🔄
🔌 Plug-and-Play - Just add a pretrained diffusion model, whether for images, text, audio, or graphs, and you're all set! ✨

🏗️ Overview of Implicit *h*-Edit

🔬 Experiments

We showcase h-Edit's capabilities in three settings: text-guided editing (conditional scores), face swapping (external reward models), and combined text-guided & style editing (both). Each experiment is linked below.

• 📝 Text-Guided Editing

• 👥 Face Swapping

• 🎨 Combined Text-Guided & Style Editing
