Image template matching is applied to various fields such as industrial image applications. Increment Sign Correlation (ISC) is one of image template matching methods. This method is robust to shading and occlusion. This paper proposes a method for image template matching that is based on Directable Increment Sign Correlation (DISC). ISC compares gray-levels of neighboring pixels to the horizontal direction. In the proposed method, the pixel with the maximum difference of gray-level between an objective central pixel in eight neighboring pixels. The experimental results show that the proposed method is robust to inclination, noise, occlusion and off-focus in comparison with ISC.
