  • Patent number: 11961229
    Abstract: In this invention, a control unit in an ophthalmic image processing device acquires an ophthalmic image captured by an ophthalmic image capture device (S11). The control unit, by inputting the ophthalmic image into a mathematical model that has been trained by a machine-learning algorithm, acquires a probability distribution in which the random variables are the coordinates at which a specific site and/or a specific boundary of a tissue is present within a region of the ophthalmic image (S14). On the basis of the acquired probability distribution, the control unit detects the specific boundary and/or the specific site (S16, S24).

  • Patent number: 11745488
    Abstract: [Object] To provide a method for the production of a thin plate-like laminate having a film-like resin layer in which a concave/convex shape can stably be formed with high accuracy on the film-like resin layer laminated on a thin plate-like substrate. [Achieving Means] There are provided a step of creating a mold retention structure 100 in which molds 110, which have been heated to a thermal deformation temperature of a film-like resin composition 84, are arranged on both surface sides of a workpiece 85, and a step of introducing the mold retention structure in which the heated molds are arranged between two compression rollers 52, 54 and compressing outer surfaces of the molds by rotating the compression rollers to integrally thermocompression-bond the film-like resin composition and a substrate 81 to form a thin plate-like laminate 80 having a film-like resin layer 82.
