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.

Abstract: 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.

Abstract: A print image synthesizing device compensates for distortion of at least one of a first print impression of an object and a second print impression of the same object to approximate the first print impression and the second print impression with each other. Portions of the first print impression and the second print impression are selected to generate one synthesized print image of the object.
