• Title: NeRF-Insert: 3D Local Editing with Multimodal Control Signals
• Authors: Benet Oriol Sabat, Alessandro Achille, Matthew Trager, Stefano Soatto,
• Abstract summary: NeRF-Insert is a NeRF editing framework that allows users to make high-quality local edits with a flexible level of control. We cast scene editing as an in-painting problem, which encourages the global structure of the scene to be preserved. Our results show better visual quality and also maintain stronger consistency with the original NeRF.

• Abstract: We propose NeRF-Insert, a NeRF editing framework that allows users to make high-quality local edits with a flexible level of control. Unlike previous work that relied on image-to-image models, we cast scene editing as an in-painting problem, which encourages the global structure of the scene to be preserved. Moreover, while most existing methods use only textual prompts to condition edits, our framework accepts a combination of inputs of different modalities as reference. More precisely, a user may provide a combination of textual and visual inputs including images, CAD models, and binary image masks for specifying a 3D region. We use generic image generation models to in-paint the scene from multiple viewpoints, and lift the local edits to a 3D-consistent NeRF edit. Compared to previous methods, our results show better visual quality and also maintain stronger consistency with the original NeRF.

  We introduce a novel approach to quickly edit a 3D model from a single reference view. Our technique first segments the edit image, and then matches semantically corresponding regions across chosen segmented dataset views. A color or texture change from a particular region of the edit image can then be applied to other views automatically in a semantically sensible manner.

We then propose a Region-IoU scheme for precise image layer extraction from an off-the-shelf segment model.

  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.

  We present a novel semantic-driven NeRF editing approach, which enables users to edit a neural radiance field with a single image. To achieve this goal, we propose a prior-guided editing field to encode fine-grained geometric and texture editing in 3D space. Our method achieves photo-realistic 3D editing using only a single edited image, pushing the bound of semantic-driven editing in 3D real-world scenes.

  We propose a method for editing NeRF scenes with text-instructions. Given a NeRF of a scene and the collection of images used to reconstruct it, our method uses an image-conditioned diffusion model (InstructPix2Pix) to iteratively edit the input images while optimizing the underlying scene. We demonstrate that our proposed method is able to edit large-scale, real-world scenes, and is able to accomplish more realistic, targeted edits than prior work.
