REVIEW OF PHASE BASED IMAGE MATCHING

Abstract

This paper review the phase based image matching method. A major approach for image matching is to extract feature vectors corresponding to given images and perform image matching based on some distance metrics. One of the difficult problem with this feature based image matching is that matching performance depends upon many parameters in feature extraction process. So this paper reviews the phase based image matching methods in which 2D DFTs of given images are used to determine resemblance between given two images. This method has been successfully applied in IRIS recognition, fingerprint recognition, palm print recognition successfully.
