  • Publication number: 20230410486
    Abstract: The present technology relates to an information processing apparatus, an information processing method, and a program that enable efficient relearning of a recognition model. An information processing apparatus includes: a collection timing control unit configured to control a timing to collect a learning image candidate that is an image to be a candidate for a learning image to be used in relearning of a recognition model; and a learning image collection unit configured to select the learning image from among the learning image candidates that have been collected, on the basis of at least one of a feature of the learning image candidate or a similarity to the learning image that has been accumulated. The present technology can be applied to, for example, a system that controls automated driving.

  • Publication number: 20190087961
    Abstract: A signal identifying device according to an embodiment includes a traffic light extractor, a lighting region extractor, and an identifier. The traffic light extractor extracts a region of a traffic light in a captured image. The lighting region extractor extracts a lighting region in the captured image. The identifier performs processing for identifying a lighting color of the traffic light on the basis of a position of the lighting region in the region of the traffic light.

  • Publication number: 20180075291
    Abstract: A method for carrying out a biometrics authentication includes detecting an object from a first image including the object, detecting feature points of the object in the detected object, generating a second image based on the feature points, wherein the second image is a normalized image of the object that is obtained by rotating and resizing the object in the first image, determining whether or not the object in the second image faces front, calculating a feature value of the object upon determining that the object in the normalized image faces front, and comparing the calculated feature value with a reference feature value for the biometrics authentication.

  • Patent number: 9881204
    Abstract: A method for determining authenticity of an object includes, detecting the object included in each of a plurality of two-dimensional images captured at different angles, detecting one or more feature points in the detected object, generating three-dimensional data representing a surface around each of the one or more feature points, generating a similarity value of the generated three-dimensional data relative to referential three-dimensional data, with respect to each of the one or more feature points, and determining whether or not the object is a real object, based on the similarity value generated with respect to each of the one or more feature points.

  • Patent number: 9858471
    Abstract: An identification apparatus has an extraction unit comprising: an extraction unit; an acquisition unit; and an identification unit. The extraction unit extracts, from an object region in an image, a candidate region including candidate points of a predetermined object using parallax information. The acquisition unit acquires a characteristic value based on image information in the candidate region. The identification unit that identifies whether or not the candidate region includes the predetermined object based on similarity between the characteristic value and a reference characteristic value.
