An image processing deviceincludes: a normal image acquisition meanswhich acquires a normal image including an object for inspection in a normal condition; an anomaly simulated image generation meanswhich inserts, into the normal image, a simulated image of an anomaly feature of the object for inspection in an anomaly condition to generate an anomaly simulated image; and a model learning meanswhich, using the normal image and the anomaly simulated image, learns a reproduction model for generating, from part of an image containing the object for inspection, a reproduction image is an image including at least a predetermined region of the object for inspection in which the predetermined region in a normal condition is reproduced.

Image processing device, image processing method, and image processing program

A network-diagram rendering system for rendering a network diagram including nodes and links as elements of a network configuration is provided with: an index calculation unit () which calculates, for each node, an index indicating a degree that the node is a primary node in the network configuration, using network configuration information as information to be obtained from the network configuration; and a primary node coefficient setting unit () which sets a primary node coefficient for the node to be higher as the index increases, the primary node coefficient being a value indicating a degree of not changing a rendering position of a network diagram associated with a change in the network configuration.

Network-diagram rendering system, network-diagram rendering method, and network-diagram rendering computer readable medium

The objective of the invention is to enable sharing, between layers in a network in which the layers are used to perform communications, resource information and information required for using paths. A network control system includes: a lower layer information storage unit, a lower layer control information conversion unit, an upper layer information storage unit, an upper layer control information conversion unit, an integrated layer information storage unit and a layer integration unit. The layer integration unit integrates, as virtual links, the information of flows, which are representative of communications among terminals in the lower layer, with the network information of the upper layer, thereby constituting the network information of the integrated layer. Further, the layer integration unit performs reciprocal exchanges of network information among the integrated layer information storage unit, the lower layer information storage unit and the upper layer information storage unit, said reciprocal exchanges including a process of giving, as the attribute information of the ports of the upper layer, label information required for using the virtual link provided by the lower layer.

Network control system, control device, network information management method, and storage

A communication system includes a control apparatus that controls communication apparatus(s) included in a hierarchical network, and a first communication apparatus that forms links in a first layer of the network and performs processing related to communication flows based on a first packet handling operation. The control apparatus determines destinations to accommodate communication flows specified according to the first packet handling operation, based on information related to a second layer that differs from the first layer.

Communication system, control apparatus, control method and program

A communication system includes a first control unit configured to change setting of a communication node(s) belonging to a first hierarchical network, in response to a setting request for the first hierarchical network and to change a topology of a second hierarchical network formed by using the first hierarchical network, and a second control unit configured to change setting of a communication node(s) belonging to the second hierarchical network, using the topology of the second hierarchical network after the change.
