Abstract
In a template matching method, a region that has a plurality of normalized reference template images as vertex template images in a space of a template-pixel-size dimension is considered, and the vertex template images are linearly interpolated by a parameter w to provide a normalized interpolated template image of a magnitude 1 in the space. Then, matching between the normalized interpolated image and a search image is performed using a normalized correlation therebetween as a similarity measure, by which is obtained a parameter that provides the maximum normalized correlation value, and this normalized correlation value is determined as the maximum one.
