Abstract:
A map information creation device for presenting information at an appropriate time includes: an operation obtaining unit which obtains operation information indicating (i) each of positions passed through by a movable body that is moved by a user and (ii) a frequency of an operation performed on a device by a user of the movable body when the movable body is at the position; a determining unit which determines, for each of positions on a map, whether or not information presentation is allowed, based on the frequency at the position indicated by the operation information; and a creating unit which creates the map information indicating a result of the determination by the determining unit for each position on the map.
Abstract:
A presentation information learning method for performing learning for presenting information to a driver of a movable body, the presentation information learning method including: obtaining a result of a response from a driver to a presentation information item which is an information item included in a plurality of presentable information items and presented to the driver; identifying a driving load on the driver; and performing the learning by updating a reference information item associated with the presentation information item from among reference information items which are associated one-to-one with a plurality of presentable information items and are referred to for judging whether or not the presentation information items are to be presented, based on the driving load identified and the obtained result of the response.
Abstract:
A risk analyzer analyzing risk of a system including N (natural number greater than or equal to 2) elements connected includes: an inputter receiving, as inputs, a cost of each N element for increasing a safety degree against a threat to security, a connection relationship of at least part of the N elements, an entry point being an element serving as an entry to the system, and a defense target being an element protected in the system; an identifier identifying, based on the cost of each N element and the connection relationship, a target element of one or more elements requiring a minimum total cost necessary for cutting off a target path from the entry point to the defense target by increasing a safety degree of one or more elements on the target path to a threshold value or more; and an outputter outputting element information indicating the target element.
Abstract:
An abnormality in a manufacturing system is detected without extensive modification to the existing manufacturing systems. The data analysis device includes: a receiver configured to receive a packet transmitted between a manufacture control device and a manufacturing device; an analyzer configured to obtain the type of data included in a payload of the received packet from an IP address and a port number included in a header of the packet; a selector configured to select, based on the type of the data obtained by the analyzer, a syntax or rule corresponding to the type of the data; and a determiner configured to determine that the manufacturing system has an abnormality if the data included in the payload does not follow the syntax or rule corresponding to the type of the data.
Abstract:
When compression encoding processing of an image is performed in units of macroblocks using a pipeline structure, an application of a skip mode or the like according to MPEG4AVC to compression encode an encoding target block requires motion vectors and the like of adjacent blocks of the encoding target block. However, depending on a structure of the pipeline stages, the motion vectors may not be determined. In such cases, the skip mode cannot be applied to compression encode the encoding target block. This problem can be solved by (i) calculating all motion information candidates, of the encoding target block, corresponding to all motion information selectable by a previous block of the encoding target block, and (ii) selecting, as the motion information of the encoding target block in the skip mode, the motion information corresponding to the motion information determined for the previous block.
Abstract:
To provide an image decoding apparatus that suppresses overhead of parallel processing to improve parallelization efficiency and reduce circuit costs, while solving neighboring macroblock dependencies. The image decoding apparatus (100) includes first and second decoding circuits (101, 102) having a transfer unit that transfers right neighborhood information or left neighborhood information, and first and second transfer completion detection units (104, 105) that respectively detect whether or not the left neighborhood information or the right neighborhood information has been transferred to the first and second decoding circuits (101, 102). Each of the first and second decoding circuits (101, 102) decodes a decoding target macroblock positioned at an edge of a region, when the transfer of the left neighborhood information or the right neighborhood information is detected. A boundary line between regions is orthogonal to a decoding direction corresponding to an order in which macroblocks adjacent to each other are sequentially decoded.
