  • Publication number: 20200294260
    Abstract: According to one embodiment, an image processing device includes storage and a processor. The storage stores a statistical model generated by learning bokeh produced in a first image affected by aberration of an optical system, the bokeh changing nonlinearly in accordance with a distance to a subject in the first image. The processor obtains a second image affected by the aberration of the optical system. The processor inputs the second image to the statistical model and obtains distance information indicating a distance to a subject in the second image.

  • Patent number: 10571246
    Abstract: According to one embodiment, an image processing apparatus includes a memory and one or more processors. The one or more processors are electrically connected to the memory, and calculate blur correction information to make a blur of a first shape of an object approach a blur of a second shape of the object. The first shape of the object is contained in a first component image of one image. The second shape of the object is contained in a second component image of the one image. The one or more processors calculate a distance between an imaging device and the object based on an image distance when the one image is captured and the blur correction information. The image distance is a distance from a lens up to an image forming surface of the object.

  • Publication number: 20200059495
    Abstract: A method manages data traffic within a network having controllers that each control a part of the network having a forwarding element (FE), the controllers being connected to a reference monitor (RM) for enforcing a security policy. The method includes: receiving a rule request by a controller and transmitting it its RM; the RM checking the rule request for policy compliance and authorizing a poly compliant part of the rule request. When the rule request has an outside modification: the controller contacts controllers impacted by the outside modification for obtaining an authorization, and upon receipt of authorization, sending the controller sends the modifications and authorizations to the impacted controllers to implement the modification in their FE.
