Patent number: 9984303Abstract: Provided is a technique for, even when the lightness of an image contained in a video changes, accurately separating the background of the image and an object in the background and thus efficiently collecting images that contain a target object to be detected, and also suppressing the amount of data communicated between a terminal device and a server. In the present invention, a terminal device accurately separates the background of an image and an object (i.e., a target object to be detected) in the background so as to simply detect the object in the background, and transfers to a server only candidate images that contain the detected object. Meanwhile, as such simple target object detection may partially involve erroneous detection, the server closely examines the candidate images to identify the target object to be detected, and thus recognizes the object.Type: GrantFiled: May 19, 2016Date of Patent: May 29, 2018Assignee: Hitachi, Ltd.Inventors: Hideharu Hattori, Tatsuhiko Kagehiro, Yoshifumi Izumi

Patent number: 7199714Abstract: In goods genuineness/counterfeit discrimination using IC tags, contradictory problems of the reliability and lifetime of the IC tags and the accuracy of goods genuineness/counterfeit discrimination are solved and circulation of goods mounted with defective IC tags is prevented. A ratio of a number of IC tags having sent information indicative of the fact that the IC tags are mounted on the same object member to a number of IC tags from which the information is to be sent originally is determined and the genuineness/counterfeit discrimination is performed with the ratio. With regard to adopting a combination of genuineness/counterfeit discrimination, information necessary for detection is added to goods and information of the inspection area is stored in the IC tags. When the number of defective IC tags is large, goods mounted with the IC tags is collected.Type: GrantFiled: January 11, 2005Date of Patent: April 3, 2007Assignee: Hitachi, Ltd.Inventors: Hiroshi Sako, Tatsuhiko Kagehiro, Hiroto Nagayoshi, Satomi Baba
