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.

Future research will consider applying kernel methods, such as the multiclass Kernel Fisher Analysis (KFA) method presented in [9], to replace the EFM method for improving face recognition performance. The hybrid color space improves face recognition performance.
