Phase-Based Iris Identification

A major approach for iris recognition today is to generate feature vectors corresponding to individual iris images and to perform iris matching based on some distance metrics. One of the difficult problems in feature-based iris recognition is that the matching performance is significantly influenced by many parameters in feature extraction process, which may vary depending on environmental factors of image acquisition. We present an efficient algorithm for iris recognition using phase-based image matching. This version is the first release on CNET Download.com.
