Iris Image Denoising With Contourlet Transform

The purpose in this paper is using a Contourlet transform and for denoising iris image. First in this paper we segment the image with Daugman methods. Then we try mapping the iris disk to 64×512 pixels with using convert polar coordinates to Cartesian. We applied preprocessing before the feature extraction that will improve the efficiency of image in feature extraction stage. The results show that the signal to noise when we used form Contourlet for image denoising is better that when we used other filter for image denoising.
