• Title: LASPA: Latent Spatial Alignment for Fast Training-free Single Image Editing
• Authors: Yazeed Alharbi, Peter Wonka,
• Abstract summary: We present a training-free approach for textual editing of real images using diffusion models. We demonstrate how the diffusion process is amenable to spatial guidance using a reference image, leading to semantically coherent edits. Our method achieves 62-71% preference in a user-study and significantly better model-based editing strength and image preservation scores.

• Abstract: We present a novel, training-free approach for textual editing of real images using diffusion models. Unlike prior methods that rely on computationally expensive finetuning, our approach leverages LAtent SPatial Alignment (LASPA) to efficiently preserve image details. We demonstrate how the diffusion process is amenable to spatial guidance using a reference image, leading to semantically coherent edits. This eliminates the need for complex optimization and costly model finetuning, resulting in significantly faster editing compared to previous methods. Additionally, our method avoids the storage requirements associated with large finetuned models. These advantages make our approach particularly well-suited for editing on mobile devices and applications demanding rapid response times. While simple and fast, our method achieves 62-71\% preference in a user-study and significantly better model-based editing strength and image preservation scores.

  We analyze reconstruction from a structural perspective and propose a novel approach that replaces traditional cross-attention with uniform attention maps. Our method effectively minimizes distortions caused by varying text conditions during noise prediction. Experimental results demonstrate that our approach not only excels in achieving high-fidelity image reconstruction but also performs robustly in real image composition and editing scenarios.

  We focus on a popular line of text-based editing frameworks - the edit-friendly'' DDPM-noise inversion approach. We analyze its application to fast sampling methods and categorize its failures into two classes: the appearance of visual artifacts, and insufficient editing strength. We propose a pseudo-guidance approach that efficiently increases the magnitude of edits without introducing new artifacts.

  A commonly adopted strategy for editing real images involves inverting the diffusion process to obtain a noisy representation of the original image. Current methods for diffusion inversion often struggle to produce edits that are both faithful to the specified text prompt and closely resemble the source image. We introduce a novel and adaptable diffusion inversion technique for real image editing, which is grounded in a theoretical analysis of the role of $eta$ in the DDIM sampling equation for enhanced editability.

  We introduce and address a novel research direction: can the process of distilling GANs from diffusion models be made significantly more efficient? First, we construct a base GAN model with generalized features, adaptable to different concepts through fine-tuning, eliminating the need for training from scratch. Second, we identify crucial layers within the base GAN model and employ Low-Rank Adaptation (LoRA) with a simple yet effective rank search process, rather than fine-tuning the entire base model. Third, we investigate the minimal amount of data necessary for fine-tuning, further reducing the overall training time.
