Abstract: Provided is a method of training a neural radiance field and producing a rendering of a 3D scene from a novel viewpoint with view-dependent effects. The neural radiance field is initially trained using a first loss associated with a plurality of unmasked regions associated with a reference image and a plurality of target images. The training may also be updated using a second loss associated with a depth estimate of a masked region in the reference image. The training may also be further updated using a third loss associated with a view-substituted image associated with a respective target image. The view-substituted image is a volume rendering from the reference viewpoint across pixels with view-substituted target colors. In some embodiments, the neural radiance field is additionally trained with a fourth loss. The fourth loss is associated with dis-occluded pixels in a target image.

Abstract: A method for editing a local area of a target image using a diffusion model, includes: receiving an input image; receiving a text instruction to edit the input image; generating a relevance map based on the diffusion model and the text instruction; generating a rendered image by performing a relevance guided image editing method on the input image, based on the generated relevance map; and providing, to the user, the generated rendered image.

Abstract: An electronic device includes: a camera; a memory; a processor to obtain a plurality of multiview color images of the object; obtain, from the latent field about the object, a plurality of multiview latent images and a plurality of camera parameters respectively corresponding to the plurality of multiview latent images; based on the plurality of multiview latent images and the plurality of camera parameters, render a first feature map about the object by using a latent field and an autoencoder; based on the first feature map about the object, train the improved NeRF by performing iterative operations; receive a request for a novel view of the object; generate, by using the improved NeRF, a second feature map from the novel view of the object; and generate, by a decoder of the autoencoder, an image about the novel view of the object based on the second feature map.

Abstract: A computer-implemented method of configuring an electronic device for inpainting source three-dimensional (3D) scenes, includes: receiving the source 3D scenes and a user's input about a first object of the source 3D scenes; generating accurate object masks about the first object of the source 3D scenes; and generating inpainted 3D scenes of the source 3D scenes by using an inpainting neural radiance field (NeRF) based on the accurate object masks.
