- Abstract summary: We focus on spatial control-based geometric manipulations and introduce a method to consolidate the editing process across various views.
We introduce QNeRF, a neural radiance field trained on the internal query features of the edited images.
We refine the process through a progressive, iterative method that better consolidates queries across the diffusion timesteps.

- Abstract: Large-scale text-to-image models enable a wide range of image editing
techniques, using text prompts or even spatial controls. However, applying
these editing methods to multi-view images depicting a single scene leads to
3D-inconsistent results. In this work, we focus on spatial control-based
geometric manipulations and introduce a method to consolidate the editing
process across various views. We build on two insights: (1) maintaining
consistent features throughout the generative process helps attain consistency
in multi-view editing, and (2) the queries in self-attention layers
significantly influence the image structure. Hence, we propose to improve the
geometric consistency of the edited images by enforcing the consistency of the
queries. To do so, we introduce QNeRF, a neural radiance field trained on the
internal query features of the edited images. Once trained, QNeRF can render
3D-consistent queries, which are then softly injected back into the
self-attention layers during generation, greatly improving multi-view
consistency. We refine the process through a progressive, iterative method that
better consolidates queries across the diffusion timesteps. We compare our
method to a range of existing techniques and demonstrate that it can achieve
better multi-view consistency and higher fidelity to the input scene. These
advantages allow us to train NeRFs with fewer visual artifacts, that are better
aligned with the target geometry.
