In this paper we target the adaptive source driven 3D scene editing task by proposing a CustomNeRF model that unifies a text description or a reference image as the editing prompt. However obtaining desired editing results conformed with the editing prompt is nontrivial since there exist two significant challenges including accurate editing of only foreground regions and multi-view consistency given a single-view reference image. 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 aimed at foreground-only manipulation while preserving the background. For the second challenge we also design a class-guided regularization that exploits class priors within the generation model to alleviate the inconsistency problem among different views in image-driven editing. Extensive experiments show that our CustomNeRF produces precise editing results under various real scenes for both text- and image-driven settings.
