Abstract: An image matching apparatus matching a first image against a second image includes an acquiring unit, a generating unit, and a determining unit. The acquiring unit acquires a frequency feature of the first image and a frequency feature of the second image. The generating unit synthesizes the frequency feature of the first image and the frequency feature of the second image, and generates a quantized synthesized frequency feature in which a value of an element is represented by a binary value or a ternary value. The determining unit calculates a score indicating a degree to which the quantized synthesized frequency feature is a square wave having a single period, and matches the first image against the second image based on the score.

Abstract: An information processing device, to be used in an image capturing device that illuminates an object by an illumination means and captures reflected light from the object as a reflection image by a capturing means, includes a determination means for determining an irradiation angle range for irradiating the object by the illumination means, on the basis of two types of inclination statistic values that are values corresponding to the inclination distribution of the unevenness existing on a surface of the object.

Abstract: There is provided a moving object detection technique capable of improving accuracy of detecting a moving object from video photographed by a moving camera. A moving object detection apparatus 10A according to an aspect of the present disclosure is provided with: a receiving portion 11 that receives video taken by an image capturing apparatus provided in a mobile body; a first calculation portion 13 that calculates first moving-object scores based on a motion of one or more pixels of image included in the video; a second calculation portion 15 that calculates second moving-object scores based on a background model and the image, wherein the background model is updated based on the image and the motions of the pixels; and a detection portion 16 that detects a moving object from the image based on the first scores and the second scores.

Abstract: An individual identification apparatus includes a setting means for setting an imaging condition for imaging a matching area of an object by a camera, an acquisition means for acquiring a matching image that is an image obtained by imaging the matching area of the object by the camera, a matching means for performing matching between the matching image and a registration image registered in advance, and a control means. The control means repeats processing of acquiring the matching image by the acquisition means and matching between the matching image and the registration image by the matching means, while changing the imaging condition set by the setting means, and determines an imaging condition in which a matching degree between the matching image and the registration image becomes a preset threshold or larger. The matching means identifies an individual based on the matching image captured under the determined imaging condition.

Abstract: An individual identification system includes an acquiring means and a determining means. The acquiring means is configured to acquire a matched image obtained by shooting part of a predetermined region of a matching target object. The determining means is configured to calculate a score representing a degree to which a partial image similar to the matched image exists in a registration image obtained by shooting a predetermined region of a registration target object, and determine based on the score whether or not the matching target object is identical to the registration target object.

Abstract: An image capturing device, configured to illuminate an object by an illumination means and capture reflected light from the object as a reflection image by a capturing means, includes an irradiation angle range determination means. The irradiation angle range determination means determines, assuming that a group of pieces of unevenness existing at the same position on the surfaces of a plurality of individuals of an object is an unevenness group, an irradiation angle range for irradiating the object by the illumination means, on the basis of a statistic value of the inclination angles of the unevenness group in which variations in the inclination angles of the unevenness between individuals is larger than other unevenness groups, among the plurality of unevenness groups.

Abstract: An individual identification apparatus that identifies an individual product having a pattern of irregularities randomly formed on a surface thereof includes an imaging unit and an extracting unit. The imaging unit is configured to acquire an image obtained by capturing a date mark formed on the product. The extracting unit is configured to extract a feature value related to the pattern of the irregularities from the image as data identifying the individual product.

Abstract: An information processing apparatus (2000) acquires state information representing states of persons, for a first person and a second person associated with the first person. The information processing apparatus (2000) determines whether a predetermined condition regarding states of the first person and the second person is satisfied, by using state information of the first person and state information of the second person. The information processing apparatus (2000) sends a notification of recommending at least the first person to take a break when the predetermined condition is satisfied.
