摘要： An method of operating a display apparatus is provided. The operating method includes calculating a confidence of a result obtained by performing light field rendering on each of pixels of a display panel based on positions of a left eye and a right eye, determining a weight kernel of a corresponding pixel based on the confidence, and adjusting a brightness of a pixel corresponding to each of the left eye and the right eye based on the weight kernel.

摘要： A processor-implemented method includes obtaining an input image, predicting light source color information of a scene corresponding to the input image and a panoramic image corresponding to the input image using an image processing model, and generating a rendered image by rendering the input image based on either one or both of the light source color information and the panoramic image.

摘要： A method of playing back an image in a display device obtains a stereo image corresponding to both eyes of a user including a left eye and a right eye, obtains positions of the eyes determines warping transform information corresponding to the positions of the eyes based on a database (DB) provided in advance based on a curvature of an display plane of the display device, warps the stereo image by applying the warping transform information to the stereo image, determines pixel values of a display panel included in the display device from the warped stereo image by performing light field rendering based on the positions of the eyes, and reproduces the determined pixel values on the display panel.

摘要： A three-dimensional (3D) rendering method and apparatus to render a 3D scene is disclosed. The 3D rendering apparatus determines color values of vertices shaded by a direct virtual light source, establishes one or more locations of one or more indirect virtual light sources in polygonal areas formed by the vertices based on the determined color values of the vertices, and renders a 3D scene based on the one or more indirect virtual light sources disposed at the determined one or more locations.

摘要： A method and apparatus for processing augmented reality (AR) including determining a compensation parameter to compensate for light attenuation of visual information caused by a display area of an AR device as the visual information corresponding to a target scene is displayed through the display area, generating a background image without the light attenuation by capturing the target scene using a camera of the AR device, generating a compensation image by reducing brightness of the background image using the compensation parameter, generating a virtual object image to be overlaid on the target scene, generating a display image by synthesizing the compensation image and the virtual object image, and displaying the display image in the display area.

摘要： A processor-implemented method with pose estimation includes: determining depth data by sensing a depth of a target scene comprising planes orthogonal to each other; determining normal vectors corresponding to depth points of the depth data; determining orientation data of a device by comparing the normal vectors to orientation candidates; and determining position data of the device based on distances from the device to the planes.

摘要： A processor-implemented method includes: estimating, from frame images of consecutive frames acquired from one or more sensors, short-term ego-motion information of the one or more sensors; estimating long-term ego-motion information of the one or more sensors from the frame images; determining attention information from the short-term ego-motion information and the long-term ego-motion information; and determining final long-term ego-motion information of a current frame, of the consecutive frames, based on the long-term ego-motion information and the attention information.
