A REVIEW ANALYSIS OF DTC WAVELET TRANSFORM BASED IRIS RECOGNITION

ABSTRACT: In this paper a review analysis of DTC wavelet transform based iris recognition the dual tree complex wavelet transform (DT CWT), a subset of discrete wavelet transform generates complex coefficients by employing a dual tree of ripple filters to get their true and unreal parts. This presents restricted repetitiveness (2m : 1 for m-multidimensional signals) and permits the transmute to furnish close shift stability and directionally exclusive filters (properties lacking within the ancient wavelet transform) while preserving the usual properties of good reconstruction and procedure efficiency with good well-balanced frequency responses.
