Face Recognition technology have lead to perfection since many years. Now Face recognition technology is the best of all technology available where the large no of database is required to identify with easy, user friendly process. The Face technology has been made to safely recognize persons, independent of variances that appear to human faces. Face Recognition technology handles pose, mimic, aging variance as well as variances coming from a new hair style, glasses or temporary lighting changes.
The independency can never be 100% based on the nature of biometrics, however algorithmic leadership, optimizing and fine tuning over a very long period created the best of class variance independency, i.e. it created excellent verification and identification results. Performance, i.e. accuracy and reliability of the recognition engine, is the key to the quality of face recognition systems.
