Consistent-Inversion: Reverse Consistency Guidance for Structure-Preserving Visual Editing

2026-06-05 · Source: Computer Vision and Pattern Recognition · Field: Technology & Digital — Artificial Intelligence & Machine Learning, Computer Vision · Depth: Expert, quick

Summary

Consistent-Inversion is a training-free reverse consistency guidance framework designed for structure-preserving visual editing using text-guided diffusion models. It addresses limitations in current inversion-based editors where reusing a fixed inverted source latent can lead to trajectory mismatch, damaging background details or over-constraining edits. Instead of a fixed initialization, Consistent-Inversion checks if an intermediate target trajectory can be reversed towards the source inversion trajectory under the source prompt. This involves constructing an auxiliary target-side noise representation, performing source-guided reverse denoising, and applying the resulting reverse consistency discrepancy as a correction signal during early target denoising steps. The method does not update model parameters, is compatible with existing inversion-based editors, and incurs only a small inference overhead when applied sparsely. Experiments on PIE-Bench show it improves background and structural fidelity under a unified SD3.5 protocol, maintaining target-prompt alignment, and is compatible with classical Stable-Diffusion inversion pipelines.

Key takeaway

For Machine Learning Engineers developing text-guided visual editing tools, Consistent-Inversion offers a robust solution to common structural preservation challenges. If you are struggling with background damage or over-constrained edits in inversion-based pipelines, consider integrating this training-free reverse consistency guidance. It improves structural fidelity and background preservation without updating model parameters, ensuring your edits maintain target-prompt alignment with minimal inference overhead.
