  • Publication number: 20190180116
    Abstract: According to one embodiment, a gradient estimation device includes one or more processors. The processors acquire a first image and a second image obtained by photographing a surface of an object. The processors extract, from the first image, a first pixel indicating a boundary of an object in a direction different from a gradient direction of the surface, and extract a second pixel corresponding to the first pixel from the second image. The processors calculate gradient magnitude of the surface by transforming at least one of the first image and the second image such that a matching degree between the first pixel and the second pixel is increased.
