Abstract: A method and apparatus with feature embedding is provided. The method includes estimating a depth map for each of plural two-dimensional (2D) input images, transforming the depth maps into three-dimensional (3D) information in a point cloud form based on an aggregation of the depth maps, and generating an embedded feature by applying the 3D information to a machine learning model, where the embedded feature includes information about a 3D shape corresponding to a 2D object in the plural 2D input images.

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: A rendering method and rendering device are provided. The rendering method includes obtaining a target image corresponding to a target view by inputting parameter information corresponding to the target view to a neural scene representation (NSR) model, determining an adjacent view that satisfies a predetermined condition with respect to the target view, obtaining an adjacent image corresponding to the adjacent view by inputting parameter information corresponding to the adjacent view to the NSR model, and obtaining a final image by correcting the target image based on the adjacent image.
