<p><P>PROBLEM TO BE SOLVED: To realize both high precision and high-speed processing. <P>SOLUTION: In collating a reference image with a registered image, with respect to the reference image, its original image is used as a high-resolution image (layer image I0) having the highest resolution, a first low-resolution image (layer image I1) is created in its lower layer, and a second low-resolution image (layer image I2) is further created in its lower layer. A registered image is read one by one, and it is determined whether to select the read registered image as a registered image candidate to be collated with the reference image on the basis of similarity between layer images having any low resolution, for example, the layer image I2 of the reference image and a layer image J2 of the registered image to narrow down registered images to be collated with the reference image. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
