Face Recognition: The Eigenface Approach
We present a range of image processing techniques as potential pre-processing
steps, which attempt to improve the performance of the eigenface method
of face recognition. Verification tests are carried out by applying
thresholds to gather false acceptance rate (FAR) and false rejection rate
(FRR) results from a data set comprised of images that present typical
difficulties when attempting recognition, such as strong variations in
lighting direction and intensity, partially covered faces and changes in
facial expression. Results are compared using the equal error rate
(EER), which is the error rate when FAR is equal to FRR. We
determine the most successful methods of image processing to be used with
eigenface based face recognition, in application areas such as security,
surveillance, data compression and archive searching.
