Object detection method and image search system

It is provided an object detection method to be performed by an image analysis device configured with a computer including a processor and a memory, the object detection method comprising: a first step of receiving, by the processor, input of an image and storing the image to the memory; a second step of extracting, by the processor, a partial area which is a part of the input image and storing the partial area to the memory; a third step of evaluating, by the processor, symmetry of the partial area using features extracted from the partial area and reflected features obtained by applying reflection to the features; and a fourth step of determining, by the processor, that the partial area is an object area including an object to be detected in a case where the symmetry of the partial area is evaluated as higher than a predetermined threshold.. . ...

Gis based compression and reconstruction of gps data for transmission from a vehicular edge platform to the cloud

Example implementations described herein are directed to a system involving a cloud architecture and an edge architecture associated with one or more vehicles. The edge architecture can involve devices associated with the one or more vehicles and can conduct edge processing to determine, from global positioning satellite (gps) information, a proximity of the first apparatus to a first geographic information system (gis) waypoint relative to a second gis waypoint, generate index information representative of the proximity of the apparatus to the first gis waypoint relative to the second gis waypoint; and transmit the index information to the cloud architecture.. ...

Sentence retrieval method and sentence retrieval system

Sentence polarity determination is used to assess whether a sentence is an affirmative expression or a negative expression, and is applied for reputation analysis, etc. Polarity determination determines whether an input sentence is affirmative or negative. ... Hitachi Ltd

Electronic control device

The objective of the present invention is to increase reliability in an electronic control device when speculative execution is performed, by reducing the risk of erroneous control by the electronic control device, said erroneous control being due to speculative execution failures (such as failures to predict a future state or failure to complete a control calculation due to the execution of an advanced control calculation) which are generated when speculative execution is performed using limited hardware resources in an electronic control device having a control period restriction. Therefore, this electronic control device, which performs a calculation in accordance with one or more external inputs, and outputs a calculation result by a prescribed time, has one or more first calculation units that perform a calculation using a current input, and one or more second calculation units that perform a calculation using a prior input that been input at a point in time prior to the current input.. ...
