Method for determining eyelash and eyelids using Hough transform and active contour for their removal in iris recognition

Abstract

Iris pattern recognition is one of the identification systems used for security systems in various tasks such as in home, secure places, computer system or bank transactions. This article presents the method for noise removal in images caused by eyelashes and eyelids to increase the accuracy of identification by using various techniques in the image processing program, MATLAB. The work consisted of image acquisition, preprocessing, and segmentation of the iris pattern using Hough transform and active contour techniques to find circles, and curves of the image. The results showed that the method can be used for determining eyelashes and eyelids for noise removal in the images.
