摘要： An image comparing apparatus receives two images to be compared with each other. For each of the two images, respective feature values of partial images in the image are determined. With respect to each partial image in one of the images, the position of a partial image that is in the other image and that has the maximum score of matching with the partial image in that one image is searched for. The search range is limited to partial images selected according to three or five different feature values determined in advance. Then, the similarity score representing the degree of similarity between these two images is calculated, based on information about a movement vector indicating a relation between a reference position for locating the partial image in one image and the maximum matching score position that is searched for with respect to the partial image. Images to be searched belong to the same category as that of the partial image. Here, the images are classified into categories based on the feature values.

摘要： Rectangular partial areas “Ri” for use in template matching in a process of determining match/mismatch between fingerprint images are spread adjacently to each other in one of the images. A boundary-including partial area is set in a portion including a crossing point of cross-shaped boundaries defined by the four neighboring partial areas. The plurality of partial areas formed of the neighboring partial areas and the boundary-including partial area are used as a template so that the number of the partial areas can be increased while ensuring a certain size of the partial area. Further, the boundary-including partial area covers the boundary between the neighboring partial areas so that continuity of image data at the boundary between the neighboring partial areas can be reflected in the determination of the match/mismatch between the images.

摘要： An image matching device capable of matching two images performs the following processes in order to shorten a processing time and reduce power consumption. Template matching is performed between a first image and a second image using a predetermined partial image of the first image, and the similarity between the two images is calculated. The similarity thus obtained is compared with a predetermined threshold. Only upon determination that the similarity obtained and the predetermined threshold neither coincide not fail to coincide with each other, the partial image used for template matching is gradually increased until the similarity and the predetermined threshold come to coincide or fail to coincide with each other. Then, template matching is performed again and the similarity between them is calculated.
