    摘要: Provided is an image generation device generating a high-quality image of an object under a pseudo light source at any desired position, based on geometric parameters generated from a low-quality image of the object. The image generation device includes: a geometric parameter calculation unit that calculates a first geometric parameter regarding a shape of a surface from light source position, viewpoint position, and geometric normal information regarding the shape; a high-resolution database unit that stores an exemplum indicating a mesostructure of a portion of the surface and has a spatial resolution higher than the geometric normal information; an exemplum expansion unit that increases the exempla to be spatially expanded; a geometric parameter modification unit that modifies the first geometric parameter using the increased exempla; and an image generation unit that generates an output image by applying the modified geometric parameter to a reflection model.

    摘要: Provided is an image generation device generating a high-quality image of an object under a pseudo light source at any desired position, based on geometric parameters generated from a low-quality image of the object. The image generation device includes: a geometric parameter calculation unit (102) that calculates a first geometric parameter regarding a surface structure from light source position, viewpoint position, and geometric normal information regarding the surface structure; a high-resolution database unit (103) that stores an exemplum indicating a mesostructure of a portion of the surface and has a spatial resolution higher than the geometric normal information; an exemplum expansion unit (104) that increases the exempla to be spatially expanded; a geometric parameter modification unit (105) that modifies the first geometric parameter using the increased exempla; and an image generation unit (106) that generates an output image by applying the modified geometric parameter to a reflection model.
