3 Uncontrolled illumination Color information and frequency features derived by means of the Discrete Fourier Transform (DFT) help improve face recognition performance. This correspondence presents a novel hybrid Color and Frequency Features (CFF) method for face recognition.

4 RIQ : R of the RGB + IQ of the YIQ
