Abstract:An accurate and robust face recognition system was developed and tested. This system exploits the feature extraction capabilities of the discrete cosine transform (DCT) and invokes certain normalization techniques that increase its robustness to variations in facial geometry and illumination. The method was tested on a variety of available face databases, including one collected at McGill University. The system was shown to perform very well when compared to other approaches.
Keywords:Face recognition  discrete cosine transform  Karhunen-Loeve transform  geometric normalization  illumination normalization  feature extraction  data compression
