<P>PROBLEM TO BE SOLVED: To provide an image determination device and a program with high determination accuracy. <P>SOLUTION: An image extraction device (100) comprises: a feature quantity extraction section (11) that extracts ruled lines and cells from an input image; an alignment section (13) that, from intervals between ruled lines in a template image and intervals between ruled lines in the input image, aligns cells and ruled lines in the template image with the cells and ruled lines in the input image; and a determination section (14) that calculates an overlapping rate of cells between the cells in the input image and the cells in the template image aligned by the alignment section (13), calculates a matching rate of the input image and the template image from the calculated overlapping rate, and when the calculated matching rate is higher than a predetermined threshold value, determines that the input image matches the template image. <P>COPYRIGHT: (C)2013,JPO&INPIT |
