Iris recognition is important automatic biometric system in the area of security. By this security, identity of each person is found. In biometric system having various types such as finger prints facial features, voice recognition, hand geometric, hand writing. In iris recognition iris is biometric component which is better in terms of stability uniquence accuracy fast and non-invasive. To improve the performance of iris recognition system this paper proposes new eyelash detection algorithm based on direction filter 1-D and 2-D algorithm is used to improved to avoid two much iris texture misclassification experimental image results show that unique codes can be generated for every eyelash image.
