Download Makalah | Jurnal Face Verification Using Modeled Eigenspectrum | Face verification is different from face identification task. Some traditional subspace methods that work well in face identification may suffer from severe over-fitting problem when applied for the verification task. Conventional dis-criminative methods such as linear discriminant analysis (LDA) and its variants are highly sensitive to the training data,which hinders them from achieving high verification accuracy. This work proposes an eigenspectrum model that allevi-ates the over-fitting problems by replacing the unreliable small and zero eigenvalues with the model values. It also enables the discriminant evaluation in the whole space to extract the low dimensional features effectively.
