Matching methods of image matching algorithm is composed of: direct use of grey degree of original image, use the feature of physical shape and use the advanced feature of the image. Classical matching algorithms contain ABS algorithm, normalized cross-correlation algorithm, moment matching method and the method based on the feature point of image. Improved methods refer to SSDA algorithm, pyramidal layered searching method and so on.
