Face recognition is a commonly used biometric strategy in various field because of its accuracy and security. However, any feasible system will have its drawbacks. Some of the drawbacks of the face recognition system include, pose change, aging, light variation and many more. By focusing on these, illumination effect is taken into account and an advanced face recognition technique is developed. The technique that is used here is Principle Component Analysis (PCA) and Fast Fourier Transform (FFT-2). This solution is applied to a smart door lock system which allows the authorized people to access the door of the house by using face recognition technique.
