Abstract: A learning apparatus includes a metric space learning unit and a case example storage unit. The metric space learning unit learns a metric space including feature vectors extracted from sets of attribute-attached image data for each combination of different attributes by using the sets of attribute-attached image data to which pieces of attribute information are added. The case example storage unit calculates feature vectors from sets of case example image data, and stores the feature vectors as case examples associated with the metric space.

Abstract: The learning device includes a metric space learning unit and a case example storage unit. The metric space learning unit learns a metric space including feature vectors extracted from attributed image data, for each combination of different attributes, using the attributed image data to which attribute information is assigned. The case example storage unit computes the feature vector from the image data for case example to store the computed feature vector as a case example associated with the metric space, and stores additional information associated with the case example.

Abstract: The disclosure is inputting a first image captured an image of an authentication target; inputting a second image captured an image of a right eye or a left eye of the target; determining whether the second image is of a left eye or a right eye of the target based on information including the first image, and outputting a determination result as left/right information in association with the second image; detecting an overlap between a region including the second image and a predetermined region in the first image; calculating a verification score by comparing characteristic information that are related to the left/right information with iris characteristic information calculated from the second image, and calculating a first weighted verification score obtained by weighting the verification score with a detection result; and authenticating a target in the second image based on the first weighted verification score, and outputting an authentication result.

Abstract: An image of an inspection surface of a product shot with a first imaging unit is divided into partial area images. For each partial area, a narrow-angle partial area image shot with a second imaging unit is acquired under shooting conditions in a pre-learning table in which the conditions and IDs are set. For each partial area, the narrow-angle partial area image suitable for inspection is selected, an inspection image is generated, and an anomaly of the inspection surface is detected based on the inspection image. For each partial area, whether each condition is effective is determined based on a frequency of the ID included by the inspection image. For each partial area, whether a predetermined condition is established is determined, and, with respect to the partial area in which the predetermined condition is established, a post-learning table is established in which only the condition determined to be effective is set.
