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: 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.

Abstract: A capacity building system is for developing visual-spatial construction planning ability. An arithmetic section has a model image display unit displaying a model image to be copied and a model image reference, a model image marks-entering request unit requesting the learner to enter marks, a model image auxiliary line-entering request unit requesting the learner to enter vertical and horizontal auxiliary lines in the model image area, an exercise image auxiliary line-entering request unit requesting the learner to enter vertical and horizontal auxiliary lines in an exercise image area, an exercise image marks-entering request unit requesting the learner to enter marks on positions, in the exercise image area, corresponding to the marks of the model image, and an exercise image forming request unit requesting the learner to form the exercise image by connecting between the marks in the exercise image area.
