Implementation Hough Method And Mahanalobis Distance In Iris Biometric Identification System

Abstract

Biometric technology is the basis of an identification system to control individuals in the under surveillance group. Biometric system provides automatic identification based on patterns or unique characteristics of each individual.In the iris-based biometric system, the common steps taken are image acquisition, image segmentation, image extraction and image recognition. Hough method is used in the segmentation step and the Mahalanobis distance method used in image recognition step. Implementation of this system using OpenCV library and as research object used Casia iris image database version 1.0 in BMP format with a size of 320 x 280 pixels.
