  • Publication number: 20240161354
    Abstract: A physical property map image generation apparatus performs: acquiring, for each pattern of a material, physical property information indicating a physical property quantity for each physical property of a product; and generating a self-organizing map and a physical property map image. A position in a map space and a physical property vector indicating a value related to a physical property quantity for each type of physical properties of the product are assigned to each node on the self-organizing map. On the physical property map image 40, each of the nodes arranged in the map space is represented by a color assigned to that node. For each node, each of two or three base color components of a color assigned to the node is determined based on a value that a physical property vector assigned to that node indicates for a physical property corresponding to that base color.
