Abstract: A method and device with light estimation are provided. A method performed by an electronic device includes generating a reference image based on image data acquired by capturing a reference object and based on a first image signal processing (ISP) setting, generating a background image based on raw image data acquired by capturing a real background in which the reference object is positioned and based on a second ISP setting, estimating light information corresponding to the background image using a light estimation model, rendering a virtual object image corresponding to the light information and the reference object, and training the light estimation model based on a difference between the reference image and the virtual object image.

Abstract: A localization method and apparatus are provided. The method comprises generating a synthetic image corresponding to a current time period based on a three-dimensional (3D) color map corresponding to an image captured at a time period prior to the current time period, and position information at the current time period time, and determining final position information at the current time period based on the synthetic image corresponding to the current time period and an image captured at the current time period.

Abstract: A shadow information storing method and apparatus is disclosed. The shadow information storing apparatus determines a shadow area through rendering a three-dimensional (3D) model based on light radiated from a reference virtual light source, determines a shadow feature value of a vertex of the 3D model based on a distance between a location of the vertex of the 3D model and the shadow area, and stores the determined shadow feature value.

Abstract: An image processing apparatus includes a calculator configured to calculate a first difference value between frames in terms of either one or both of a position and a direction of a direct light by comparing a current frame to at least one previous frame, and a determiner configured to determine that an indirect light of the current frame is to be sampled in response to the first difference value being greater than or equal to a threshold.

Abstract: A processor-implemented method for light estimation includes: estimating light information corresponding to an input image using a light estimation model; detecting a reference object in the input image; determining object information of the reference object and plane information of a reference plane supporting the reference object; rendering a virtual object corresponding to the reference object based on the light information, the object information, and the plane information; and training the light estimation model by updating the light estimation model based on a result of comparing the reference object and the rendered virtual object.

Abstract: A supersampling method includes generating a current rendered image frame by performing jittered sampling on a three-dimensional (3D) scene, based on sub-pixels of low-resolution pixels for the current rendered image frame; generating a current warped image frame by warping a previous output image frame, based on a motion vector map corresponding to a difference between the current rendered image frame and a previous rendered image frame; generating a current shifted image frame by shifting pixels of the current warped image frame, based on a change in sampling positions based on the jittered sampling; and generating a current output image frame, based on the current rendered image frame and the current shifted image frame.
