Abstract This paper proposes a template matching method maximum and minimum gray levels pixels sign matching (MMM) which is based on a comparison of the gray levels of a pair of pixels whose locations are on the pixels with the maximum and the minimum gray levels in a local area in a template image. In this method, the locations of the pixels with the maximum and the minimum gray levels are registered in a local area whose center is every pixel in a template image. The target image area is searched from the matching ratio which is obtained by the relation between the gray levels of the two pixels whose locations have been registered in the template image. The experimental results show that the proposed method had equal or better robustness to the inferior factors of objective images in comparison with the three typical conventional template matching methods.
