• Abstract: Our goal is to develop fine-grained real-image editing methods suitable for real-world applications. In this paper, we first summarize four requirements for these methods and propose a novel diffusion-based image editing framework with pixel-wise guidance that satisfies these requirements. Specifically, we train pixel-classifiers with a few annotated data and then infer the segmentation map of a target image. Users then manipulate the map to instruct how the image will be edited. We utilize a pre-trained diffusion model to generate edited images aligned with the user's intention with pixel-wise guidance. The effective combination of proposed guidance and other techniques enables highly controllable editing with preserving the outside of the edited area, which results in meeting our requirements. The experimental results demonstrate that our proposal outperforms the GAN-based method for editing quality and speed.

  We propose a novel mask-free point-based image editing method, AdaptiveDrag, which generates images that better align with user intent. To ensure a comprehensive connection between the input image and the drag process, we have developed a semantic-driven optimization. Building on these effective designs, our method delivers superior generation results using only the single input image and the handle-target point pairs.

  We present a new form of editing, termed imitative editing, to help users exercise their creativity more conveniently. We propose a generative training framework, dubbed MimicBrush, which randomly selects two frames from a video clip, masks some regions of one frame, and learns to recover the masked regions using the information from the other frame. We experimentally show the effectiveness of our method under various test cases as well as its superiority over existing alternatives.

  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 propose a CustomNeRF model that unifies a text description or a reference image as the editing prompt. To tackle the first challenge, we propose a Local-Global Iterative Editing (LGIE) training scheme that alternates between foreground region editing and full-image editing. For the second challenge, we also design a class-guided regularization that exploits class priors within the generation model to alleviate the inconsistency problem.
