A novel algorithm for a rotation invariant template matching

Scene matching of arbitrary angle rotation is a difficult problem, but important for missile guidance. The conventional structural pixel-to-pixel template matching algorithms are the process of determining the presence and the location of a real time image or an object inside a scene image under analysis by a spatial cross-correlation process. So the conventional algorithms are helpless to the problem, and cannot be used for practical purposes. An algorithm for a rotation invariant scene matching method based on isotropy of circular and cirque projection feature is proposed. Experimental results show that the proposed algorithm is more robust, and the running time reduces 1/7, or even more. Furthermore, matching ratio is 10% ~ 20% improvement than circle projection algorithm under the same condition.
