We also design a classifier to adaptively combine Dual-Schedule Inversion with different editing methods for user-friendly image editing.

• Abstract: Text-conditional image editing is a practical AIGC task that has recently emerged with great commercial and academic value. For real image editing, most diffusion model-based methods use DDIM Inversion as the first stage before editing. However, DDIM Inversion often results in reconstruction failure, leading to unsatisfactory performance for downstream editing. To address this problem, we first analyze why the reconstruction via DDIM Inversion fails. We then propose a new inversion and sampling method named Dual-Schedule Inversion. We also design a classifier to adaptively combine Dual-Schedule Inversion with different editing methods for user-friendly image editing. Our work can achieve superior reconstruction and editing performance with the following advantages: 1) It can reconstruct real images perfectly without fine-tuning, and its reversibility is guaranteed mathematically. 2) The edited object/scene conforms to the semantics of the text prompt. 3) The unedited parts of the object/scene retain the original identity.

  We present Emu Edit, a multi-task image editing model which sets state-of-the-art results in instruction-based image editing. We train it to multi-task across an unprecedented range of tasks, such as region-based editing, free-form editing, and Computer Vision tasks. We show that Emu Edit can generalize to new tasks, such as image inpainting, super-resolution, and compositions of editing tasks, with just a few labeled examples.

  We propose FEC, which consists of three sampling methods, each designed for different editing types and settings. FEC achieves two important goals in image editing task: 1) ensuring successful reconstruction, i.e., sampling to get a generated result that preserves the texture and features of the original real image. None of our sampling methods require fine-tuning of the diffusion model or time-consuming training on large-scale datasets.

They suffer from two problems: Unsatisfying results for selected regions and unexpected changes in non-selected regions.
