Image collation device, image collation method, and image collation program.

摘要

A correlation value image is created from an input image and a template image. The correlation value image is divided into positive and negative correlation value images depending on whether the pixel value is above a threshold or not, and the template image is divided into positive and negative template images depending on whether the pixel value is above a threshold or not. Positive and negative division correlation images are created by combining the positive and negative correlation value images and the positive and negative template images and used for check and judgment. For this input image and the template image, polar coordinate transformed input and template images are used.
