Matching method using the edge with the rigid assumption

In this paper, we propose the matching method using the edge image with the rigid assumption. We introduce the virtual intensity added to the edge image and regard it as energy function. It is assumed that the objects to match each other is rigid. The edges are repeatedly moved to the direction which the energy function are reduced by parallel translation and rotation. The corresponding point between two images can be found when the function is minimum. Real images include the area which have no or extreme intensity change. The proposed method is available in those cases since it uses features of the image that is the edges. We showed this advantage by the experiments of motion estimation.
