Abstract
This paper proposes a new method for image template matching that is based on the correlation between the edge-spins. The edge-spin is defined by the direction of the change of edge directions between neighboring pixels. When an edge direction rotates to the left from an objective pixel to its right neighboring pixel, the edge-spin has the value 1. When an edge direction rotates to the right, the edge-spin has the value 0. The edge-spin is a binary data that represents the rotation of the edge direction. The edge-spin is supposed to be robust to the change of brightness because the edge direction is not influenced by the liner change of brightness. The experimental results show that the proposed method has the superior reliability for the matching about most inferior experimental conditions in comparison with the conventional image template matching methods.
