Objective Iris image quality assessment is very important in iris recognition systems. Its motivation is to improve the performance of iris recognition by assessing the quality of iris samples. It is closely related to the modules of iris image acquisition, human-computer interaction, performance evaluation, adaptive iris recognition and so on. With the development of non-ideal iris recognition techniques, iris image quality-assessment methods have been widely studied in recent years. Method In order to give the researchers a comprehensive knowledge about iris image quality-assessment, state-of-the-art methods are reviewed. Result The trend, technical solution and at last, the potential pointers of the iris image quality-assessment methods and the quality driven iris recognition techniques are discussed.Conclusion With the advent of the era of big data, large scale iris recognition will become the hot topic. The study of iris image quality assessment is of great significance to promote the processing capacity of the iris recognition system.
