Using side systems to help main system in Face Recognition methods is quickly emerging.
Every method has advantages and disadvantages against others. That’s why, technology companies are combining traditional, 3D and skin texture analysis so their recognition system reaches higher rate of success.
This combined systems are offering quite advantages than normal systems. Giving more successful results in the challenges like face expressions such as smiling, frowning, blinking and beards, mustaches, eyeglasses etc.
Also to recognise in lower lightnings and dark environments; thermal cameras or normal cameras + infrared lightning are being used.
Infrared lightning is not visible to human eye but for cameras, it is lightning the environment to capture net and luminous captures.
