An Improved Iris Recognition Method Based on Discrete Cosine Transform and Gabor Wavelet Transform Algorithm

摘要

An improved Iris recognition method wasproposed by adopting the discrete cosine transform (DCT)method and Gabor wavelet transform algorithm. Thecombination of the calculus operator method, improved Houghtransform and the two-step edge detection method is adopted torealize the iris localization and extraction. The discrete cosinetransform method and the Gabor wavelet transform areutilized to form the propose improved Gabor wavelet transformfor iris localization and extraction. Finally, the nearest neighbordistance detector and Euclidean distance are used as theclassifier to realize the iris recognition. Simulation experimentsare carried out to prove the effectiveness of the proposedstrategy.
