Image collation device, image collation feature storage medium, image collation method, and image collation program

摘要

It is necessary to provide an image collation apparatus or the like that enables accurate collation. By configuring the image collation apparatus so as to use the cumulative pixel value ratio of the connected region or its sum region, which is another invariant relating to affine transformation, as a feature amount, more accurate collation can be performed. In addition, by using the relative position information of the region, it is possible to realize a more accurate collation.
