Title:
MULTI-VIEWPOINT IMAGE GENERATION DEVICE, METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/095353
Kind Code:
A1
Abstract:
One aspect of the present invention involves transforming training images that are photographed from a plurality of viewpoints into wavenumber domain training images respectively, expanding the wavenumber domain training images in the form of spherical harmonics series for each wavenumber component, generating a wavenumber domain image corresponding to a designated virtual viewpoint different from the plurality of viewpoints on the basis of the spherical harmonics series and information for specifying a direction of photography from the certain virtual viewpoint, and transforming the generated wavenumber domain image into a generated space domain image.
