| 発明の概要（英語） |
Provided are: a feature extraction method that is a method of extracting a feature that represents a characteristic of a subject, said feature being extracted from an image that has imaged the subject, said feature being extracted without relation to the shape of said subject and methods that use the extracted feature to classify and identify the subject. The feature extraction method extracts the feature from the image of the subject, said subject having been imaged by an imaging means. From the image that has imaged the subject, said feature extraction method extracts the feature by means of containing: a step in which a filter bank is created from the image a step in which a maximum brightness image is created from the filter bank a step in which a circular image region of the maximum brightness image is set, and the center (Cc) and the radius (Rc) of the circular image region are set a step in which a pixel of the maximum brightness image is projected into a three-dimensional space having as the axes thereof, (a) the ratio of the radius (Rc) and the distance (LD) extending from the pixel position (x, y) to the center (Cc), (b) the pixel brightness value ((FD (x, y)), and (c) the sum of the differences between the brightness value of the pixel and the brightness values of neighboring pixels and a step in which a frequency histogram is created from the pixel projected into the three-dimensional space. |
