Abstract: An image recognition device includes: an image processing device that acquires a feature amount from an image; and an identification device that determines whether a prescribed identification object is present in the image, and identifies the identification object. The identification device includes a BNN that has learned the identification object in advance, and performs identification processing by performing a binary calculation with the BNN on the feature amount acquired by the image processing device. Then, the identification device selects a portion effective for identification from among high-dimensional feature amounts output by the image processing device to reduce the dimensions used in identification processing, and copies low-dimensional feature amounts output by the image processing device to increase dimensions.

Abstract: An image recognition device involves successively extracting co-occurrence pairs in synchronization with a clock, setting a weighting for the portion connecting the input layer and the intermediate layer corresponding to the extracted co-occurrence pairs, and successively inputting a first vote to the input layer. Meanwhile, the intermediate layer adds and stores the successively inputted number of votes. By continuing this operation, a value the same as if a histogram were inputted to an input layer is achieved in the intermediate layer, without creating a histogram. In this way, the image recognition device of this embodiment can perform image recognition while avoiding the creation of a histogram, which consumes vast amounts of memory. As a result of this configuration, it is possible to save memory resources, simplify circuits, and improve calculation speed, and achieve an integrated circuit suitable to an image recognition device.

Abstract: An image recognition device executes a Hilbert scan of frame image data constituting moving-image data to generate one-dimensional spatial image data, and further arrays the one-dimensional spatial image data in a time direction to generate two-dimensional spatio-temporal image data that holds spatial information and temporal information. The image recognition device converts the moving-image data into the two-dimensional spatio-temporal image data while holding the spatial and temporal information. By means of a CNN unit, the image recognition device executes a convolution process wherein a two-dimensional filter is used on the spatio-temporal image data to image-recognize a behavior of a pedestrian who is a recognition object.

Abstract: A spatio-temporal image recognition device includes spatio-temporal image data generation units for converting moving-image data which continuously holds spatial information and temporal information to spatio-temporal image data, and they scan the moving-image data on scanning paths different from each other. The spatio-temporal image data generation units generate spatio-temporal image data scanned on the scanning paths different from each other and output them to an image recognition unit. The image recognition unit generates two-dimensional feature maps by individual convolution process of the spatio-temporal image data and then, integrates them, analyzes them by a neural network, and outputs an image recognition result.

The system or a terminal acquires a question message input via the terminal together with positional information associated with the question message and causes the acquired question message to be accessible to the users. The system or terminal acquires an answer message input by a respondent via the terminal as an answer to the question message and causes the acquired answer message to be accessible to the users. The system or terminal acquires positional information of the respondent and restricts the respondent accessing the question message on the basis of question positional information that is the positional information associated with the question message and respondent positional information that is the acquired positional information of the respondent.

Abstract: Posted text search systems, methods, and programs acquire an expected travel route for a mobile body and determine whether a congestion factor facility, which is a facility that causes congestion, is located around the expected travel route. The systems, methods, and programs acquire, when it is determined that the congestion factor facility is located around the expected travel route, a closer intersecting road, which is a road that is located on the side of the mobile body with respect to the congestion factor facility and that intersects the expected travel route and acquire a name of the closer intersecting road as a search target name. The systems, methods, and programs set a search word from a character string of the acquired search target name and extract a posted text that corresponds to the set search word from texts posted on a computer network.

Abstract: In this navigation apparatus, when speech recognition of inputted speech is carried out, keywords included in the content of the recognized speech are searched from a dictionary DB, and then these words are displayed as keywords of a POI search. When a correction of a keyword is required by the user, because most errors occur in the first phonetic symbol of the misrecognized word, a search of words each having phonetic symbols in which the first phonetic symbol of the misrecognized word is changed from the phonetic symbols of the word to be corrected (i.e., a search of words having one different first phonetic symbol) is carried out to present candidates for correction. In this navigation apparatus, because the displayed candidates for correction are limited to words having a different first phonetic symbol which has a high possibility of being the cause of misrecognition, the user can correct the misrecognized keyword by a simple operation.
