This paper proposes the improved eigen-decomposition template matching. The eigen-decomposition template matching is a method to detect the displacement and the rotational angle more accurately than the traditional rotational correlation matching such as the Cross-Correlation method. The proposed method calculates the correlation by matching the images which is determined by eigen decomposition of the template image to the input image instead of matching the template image to the input image directly. Furthermore, this paper proposes the method to detect the displacement and rotational angle even if the input image includes the large displacement translation and the intensity variations. The experimental results show that the proposed method can detect the displacement and rotational angle more accurately than the previous method for the image with a noise and an illumination variance.
