|20140100766||TRAFFIC DATA PREDICTION DEVICE, TRAFFIC DATA PREDICTION METHOD AND COMPUTER PROGRAM - A traffic data prediction device includes an original link traffic data storage unit (||04-10-2014|
|20140037138||MOVING OBJECT RECOGNITION SYSTEMS, MOVING OBJECT RECOGNITION PROGRAMS, AND MOVING OBJECT RECOGNITION METHODS - The moving object recognition system includes: a camera that is installed in a vehicle and captures continuous single-view images; a moving object detecting unit that detects a moving object from the images captured by the camera; a relative approach angle estimating unit that estimates the relative approach angle of the moving object detected by the moving object detecting unit with respect to the camera; a collision risk calculating unit that calculates the risk of the moving object colliding with the vehicle, based on the relationship between the relative approach angle and the moving object direction from the camera toward the moving object; and a reporting unit that reports a danger to the driver of the vehicle in accordance with the risk calculated by the collision risk calculating unit.||02-06-2014|
|20130253812||Traffic Congestion Prediction Method And Traffic Congestion Prediction Device - Provided is a traffic congestion prediction method which is able to perform a prediction process using floating information with higher accuracy. The traffic congestion prediction method includes: a step of receiving information by a prediction device; a step of predicting a route of each floating car based on the current position information and destination information received; a step of calculating, for the each floating car, a first passing time group which is a set of respective passing times at a plurality of predetermined spots on the route predicted; a step of calculating the number of existing floating cars per link based on the first passing time group, if any of a plurality of floating cars exists on the link at a predetermined time; and a step of calculating a second passing time group by use of the number of existing floating cars and a predetermined calculation technique.||09-26-2013|
|20130223737||LOCAL FEATURE AMOUNT CALCULATING DEVICE, METHOD OF CALCULATING LOCAL FEATURE AMOUNT, CORRESPONDING POINT SEARCHING APPARATUS, AND METHOD OF SEARCHING CORRESPONDING POINT - A local feature amount calculating device includes a local feature amount calculating unit that acquires a local feature amount of a feature point for each pixel by giving a vote of a strength of the direction of a pixel, which is calculated by a direction strength calculating unit, to a vote cell to which a pixel of interest belongs out of vote cells of a rotated vote cell pattern that is acquired by rotating a reference vote cell pattern by an angle corresponding to a main axis direction along a corrected edge gradient direction that is acquired by correcting an edge gradient direction of the pixel that is calculated by a direction strength calculating unit in accordance with the main axis direction.||08-29-2013|
|20120310534||DESTINATION ESTIMATING APPARATUS, NAVIGATION SYSTEM INCLUDING THE DESTINATION ESTIMATING APPARATUS, DESTINATION ESTIMATING METHOD, AND DESTINATION ESTIMATING PROGRAM - An object of this invention is to improve the accuracy of estimating a destination in a destination estimating apparatus. A destination estimating apparatus||12-06-2012|
|20120310526||NAVIGATION APPARATUS, NAVIGATION METHOD, AND NAVIGATION PROGRAM - To improve accuracy of determining whether route elements stored as a history are route elements familiar to the user, a navigation apparatus||12-06-2012|
|20120219212||FEATURE CONVERSION DEVICE, SIMILAR INFORMATION SEARCH APPARATUS PROVIDED THEREWITH, CODING PARAMETER GENERATION METHOD, AND COMPUTER PROGRAM - A bit code converter transforms a learning feature vector using a transformation matrix updated by a transformation matrix update unit, and converts the transformed learning feature vector into a bit code. When the transformation matrix update unit substitutes a substitution candidate for an element of the transformation matrix, a cost function calculator fixes the substitution candidate that minimizes a cost function as the element. The transformation matrix update unit selects the element while sequentially changing the elements, and the cost function calculator fixes the selected element every time the transformation matrix update unit selects the element, thereby finally fixing the optimum transformation matrix. A substitution candidate specifying unit specifies the substitution candidate such that a speed of transformation processing that the bit code converter performs using the transformation matrix using the transformation matrix is enhanced based on a constraint condition stored in a constraint condition storage unit.||08-30-2012|
