  • Publication number: 20210224590
    Abstract: Provided is technology for extracting a person region from an image, that can suppress preparation costs of learning data. Included are a composited learning data generating unit that generates, from already-existing learning data that is a set of an image including a person region and a mask indicating the person region, and a background image to serve as a background of a composited image, composited learning data that is a set of a composited image and a compositing mask indicating a person region in the composited image, and a learning unit that learns model parameters using the composited learning data.

  • Patent number: 10850177
    Abstract: Preliminary experience of a match at a player's perspective is enabled. A virtual environment material storage 13 has stored therein virtual environment materials for reproducing a dynamic object and a static object on a virtual environment. A dynamic object sensing unit 11 chronologically measures a position and a posture of the dynamic object in a real environment and generates position and posture information composed of one movement action. A presentation sequence acquisition unit 17 obtains a presentation sequence including position and posture information of a plurality of different kinds of dynamic objects. A virtual environment construction unit 14 synthesizes a virtual environment material of the dynamic object and a virtual environment material of the static object based on the presentation sequence to construct the virtual environment.
