The template matching is a method to search the target image area that is similar to the registered template image. The template matching is a general-purposed and simple method. But the target image must have the right position as the template image generally. Therefore it requires large computational cost when the location and the inclination of a target image area are unknown. This paper proposes a template matching method to search a target image area that has a free location and a free inclination using the two-dimensional histogram space spread by the relative edge angle at an objective pixel in the image area to the direction angle from the center of the image area to the objective pixel and the distance from the center to the objective pixels. The experimental results show that the proposed method had high reliability for matching without influence of the changes about inclinations and locations of the target image areas.
