Stripe pattern image analysis device, stripe pattern image analysis method, and program thereof

A streaked pattern image analyzing apparatus for use in an analysis of a fingerprint and the like for aiding in the identification as to whether or not an applied first streaked pattern image matches a second streaked pattern image. The apparatus comprises an image distortion modification unit for modifying data on one of the first streaked pattern image and the second streaked pattern image such that a point on a first streaked pattern image which resides on a skeleton thinned from a streak of the streaked pattern image and having a corresponding point on the second streaked pattern image is brought closer to a point on a skeleton of the second streaked pattern image corresponding to the point, and an image display unit for displaying the streaked pattern image modified by the image distortion modifying unit and the other streaked pattern image.

Method and apparatus for analyzing streaked pattern image

A streaked pattern image matching method that matches a first streaked pattern image and a second streaked pattern image includes steps of: extracting data of skeleton pixels that indicate skeletons, which are lines obtained by thinning the streaks of each streaked pattern image; establishing correspondences between skeleton pixels by specifying pixels from among skeleton pixels of the second streaked pattern image that correspond to skeleton pixels of the first streaked pattern image; and, based on skeleton pixels of the first streaked pattern image for which the process of establishing correspondence has been carried out, rating the degree of matching between the first streaked pattern image and the second streaked pattern image and calculating a score that represents the degree of matching.
