  • Publication number: 20240378833
    Abstract: An information processing apparatus (10) includes a display control unit (14) and a fitting unit (13). The display control unit (14) displays a distribution image indicating distribution of a plurality of marker points extracted from a face model of a performer in a superimposed manner on a face image of the performer. The fitting unit (13) fits the face model to the face image by using position information of a placed marker each time the marker is placed on a face of the performer after the distribution image is superimposed, and adjusts a superimposed position of the distribution image based on a fitting result.
