Patent number: 11755907Abstract: A similarity calculation unit (213) treats each of a plurality of classifications as a target classification, and calculates a similarity between a reference feature value, which is a feature value extracted from image data of the target classification, and a recognition feature value, which is a feature value extracted from recognition target data, which is image data to be recognized. An influence calculation unit (214) calculates an influence on the similarity with regard to each partial image of the recognition target data by taking as input the similarity with regard to each of the classifications and the recognition feature value. A feature identification unit (215) changes the recognition feature value in accordance with the influence.Type: GrantFiled: July 29, 2021Date of Patent: September 12, 2023Assignee: Mitsubishi Electric CorporationInventors: Eri Kataoka, Hiroshi Yokochi, Mitsuhiro Matsumoto, Mikihito Kanno, Takamichi Koide, Yosuke Watanabe

Patent number: 11430241Abstract: In an entry field extraction device, a learning unit obtains a learning model by learning, from images of a plurality of documents, features corresponding to types of the documents. A feature field extraction unit extracts, from an image of a document sample, a feature field being a field indicating a feature corresponding to a type of the document sample, using the learning model. An entry field extraction unit extracts an entry field, being a field of an entry column, from a field that remains in the image of the document sample from which the feature field extracted by the feature field extraction unit has been excluded.Type: GrantFiled: August 24, 2018Date of Patent: August 30, 2022Assignee: Mitsubishi Electric CorporationInventors: Mitsuhiro Matsumoto, Eri Kataoka, Yosuke Watanabe, Shunsuke Yamamoto, Mikihito Kanno, Takamichi Koide

Publication number: 20190050568Abstract: An activity process list (330) is a list in which an attack type identifier and an activity process identifier are associated with each other. An operation process list (340) is a list in which an operation-source process identifier and an operation-destination process identifier are associated with each other. An indirect process searching unit (230) searches for a set of indirect process identifiers using the activity process list and the operation process list, the set of indirect process identifiers corresponding to a set of activity process identifiers associated with different attack type identifiers, and corresponding to a set of an operation-source process identifier and an operation-destination process identifier.Type: ApplicationFiled: April 4, 2016Publication date: February 14, 2019Applicant: MITSUBISHI ELECTRIC CORPORATIONInventors: Eri KATAOKA, Mitsuhiro MATSUMOTO

Patent number: 8688932Abstract: In a virtual computer system controlling a disk volume and a virtual server which is connected to the disk volume, to which the area of the disk volume is allocated as a virtual disk and which executes a process using the allocated virtual disk, the virtual computer system erases information stored in the virtual disk allocated to the virtual server to be deleted correspondingly with the deletion of the virtual server. An administrative server may be provided to select a server system which is low in load from among plural server systems controlling virtual servers as a server system for erasing information stored in the virtual disk allocated to the virtual server to be deleted.Type: GrantFiled: September 14, 2012Date of Patent: April 1, 2014Assignee: Hitachi, Ltd.Inventors: Eri Kataoka, Yoshifumi Takamoto

Patent number: 8296533Abstract: In the environment of a virtual server, there is a problem in that the contents in a disk area released correspondingly with the deletion of the virtual server may be read. According to the present invention, in a virtual computer system controlling a disk volume and a virtual server which is connected to the disk volume, to which the area of the disk volume is allocated as a virtual disk and which executes a process using the allocated virtual disk, the virtual computer system erases information stored in the virtual disk allocated to the virtual server to be deleted correspondingly with the deletion of the virtual server. According to another embodiment of the present invention, an administrative serve is provided to select a server system which is low in load from among plural server systems controlling virtual servers as a server system for erasing information stored in the virtual disk allocated to the virtual server to be deleted.Type: GrantFiled: April 21, 2011Date of Patent: October 23, 2012Assignee: Hitachi, Ltd.Inventors: Eri Kataoka, Yoshifumi Takamoto
