Iris feature extraction: a survey
2013
Biometric as a technology has been proved to be a reliable means of enforcing constraint in a security sensitive environment. Among the biometric technologies, iris recognition system is highly accurate and reliable because of their stable characteristics throughout lifetime. Iris recognition is one of the biometric identification that employs pattern recognition technology with the use of high resolution camera. Iris recognition consist of many sections among which feature extraction is an important stage. Extraction of iris features is very important and must be successfully carried out before iris signature is stored as a template. This paper gives a comprehensive review of different fundamental iris feature extraction methods, and some other methods available in literatures. It also gives a summarised form of performance accuracy of available algorithms. This establishes a platform on which future research on iris feature extraction algorithm(s) as a component of iris recognition system can be based.
