Publication number: 20200011685Abstract: Route search devices and programs obtain network data including nodes and links, and link information including (i) travel times for traveling a link included in the network data, the nodes and the links representing a road network, and (ii) for each entry link or each exit link, information that identifies a value representing statistical variation of travel times for the link, the entry link being a link entering a node at one end of the link, and the exit link being a link exiting from a node at another end of the link. The devices and programs search for a recommended route by taking into account (i) a travel time to a destination, based on the network data and the link information, and (ii) cost values identified based on a representative value of travel times for a link and a value representing statistical variation of the travel times.Type: ApplicationFiled: March 28, 2018Publication date: January 9, 2020Applicants: AISIN AW CO., LTD., TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Sadahiro KOSHIBA, Kazuteru MAEKAWA, Koichi USHIDA, Hiroyuki TASHIRO, Tomohiko MASUTANI, Tomoko ARITA, Motohiro NAKAMURA, Atsushi IKENO, Yoshitaka KATO

Patent number: 6185337Abstract: In an artificial intelligence system for image recognition, a global image of an object is input from a camera or other optical pick-up device, and is processed in a global image processing means, which performs analytical processing on the global image by extracting global characteristics of the input image and evaluating consistency of the extracted global characteristics. Simultaneously, the image data is processed in a local image processing means which undertakes analytical processing on a plurality of local images defining local portions of the image to be recognized. The local image processing means is constructed by plural modules, each further defined by sub-modules, which conduct respective analyses corresponding to local images having characteristics useful in recognizing the global image, wherein each local processor extracts characteristics of an input local image and evaluates consistency of the extracted characteristic with the object to be recognized.Type: GrantFiled: December 12, 1997Date of Patent: February 6, 2001Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Hiroshi Tsujino, Edgar Koerner, Tomohiko Masutani

Patent number: 5675663Abstract: An artificial visual apparatus and method for image recognition having a simple adaptive scaling mechanism enables the definition of scale invariant visual icons in a processing area corresponding to the anterior inferotemporal cortex (AIT) in a one-step, value-based decision making process. Icon related activity states resulting from sensory filtering to a fourth stage KL filter corresponding to the V4 area are recognized independent of the scale and position of the item to be recognized within the maximum visual field. The AIT processing area controls the window of attention in the V4 area and confines further processing onto this selected spotlight. The invention presents a biologically plausible method for scale invariant mapping from the V4 stage filter to the AIT processor.Type: GrantFiled: March 21, 1996Date of Patent: October 7, 1997Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Edgar Koerner, Hiroshi Tsujino, Tomohiko Masutani
