• Authors: Chen Hou, Guoqiang Wei, Zhibo Chen
• Abstract summary: The editing performance of diffusion models tends to be no more satisfactory even with increasing denoising steps. We propose an innovative framework where a Markov module is incorporated to modulate diffusion model weights with residual features. We introduce a novel learning paradigm aimed at minimizing error propagation during the editing process, which trains the editing procedure in a manner similar to denoising score-matching.

• Abstract: Diffusion models have attained remarkable success in the domains of image generation and editing. It is widely recognized that employing larger inversion and denoising steps in diffusion model leads to improved image reconstruction quality. However, the editing performance of diffusion models tends to be no more satisfactory even with increasing denoising steps. The deficiency in editing could be attributed to the conditional Markovian property of the editing process, where errors accumulate throughout denoising steps. To tackle this challenge, we first propose an innovative framework where a rectifier module is incorporated to modulate diffusion model weights with residual features, thereby providing compensatory information to bridge the fidelity gap. Furthermore, we introduce a novel learning paradigm aimed at minimizing error propagation during the editing process, which trains the editing procedure in a manner similar to denoising score-matching. Extensive experiments demonstrate that our proposed framework and training strategy achieve high-fidelity reconstruction and editing results across various levels of denoising steps, meanwhile exhibits exceptional performance in terms of both quantitative metric and qualitative assessments. Moreover, we explore our model's generalization through several applications like image-to-image translation and out-of-domain image editing.

  Effective editing requires inverting the source image into a latent space, a process often hindered by prediction errors inherent in DDIM inversion. We introduce the Logistic Schedule, a novel noise schedule designed to eliminate singularities, improve inversion stability, and provide a better noise space for image editing. Our approach requires no additional retraining and is compatible with various existing editing methods.

We propose a pseudo-guidance approach that efficiently increases the magnitude of edits without introducing new artifacts.
