  • Publication number: 20240249523
    Abstract: The present disclosure provides systems and methods for identifying and extracting object-related effects in videos. Given an ordinary video and a rough segmentation mask overtime of one or more subjects of interest, example systems proposed herein can estimate an omnimatte for each subject—an alpha matte and color image that includes the subject along with all its related time-varying scene elements. Example implementations of the proposed models can be trained only on the input video in a self-supervised manner, without any manual labels, and are generic. For example, the models can produce omnimattes automatically for arbitrary objects and a variety of effects.

  • Publication number: 20240192498
    Abstract: A compact augmented reality (AR) display system is described herein. The AR display system includes an eyeglass frame and a pair of near-eye pupil forming catadioptric optical engines mounted to the eyeglass frame. The pair of near-eye pupil forming catadioptric optical engines are mounted to the eyeglass frame and spaced along the longitudinal axis. Each of the near-eye pupil forming catadioptric optical engines includes an image generator forming a 2D image, an optical imaging assembly, and an optical image relay assembly, which includes the image generator and the lenses or other optics to present the image correctly to the user. The pair of near-eye pupil forming catadioptric optical engines enable viewing the 2D image binocularly in 3D.

  • Patent number: 11906736
    Abstract: A display has an image generator; a partially transmissive mirror having a curved surface; a beam splitter to reflect incident light toward the curved surface; and an optical image relay that defines a path to relay light to a curved focal surface of a partially transmissive mirror, the curved focal surface is between a curved reflective surface of the partial mirror and the beam splitter. A prism has a folding surface in the optical path for light from the image generator, wherein an aperture stop for the relay lies within the prism. A first plano-aspheric lens, against the prism input surface, guides light from the image generator toward the folding surface; a second plano-aspheric lens, in optical contact against the prism output surface, directs light to the curved focal surface. The relay, curved mirror, and beam splitter form an exit pupil for viewing the scene with a 2D image superimposed.
