Wavelet–Based Face Recognition Schemes
Sabah A. · InTech eBooks · 2010
The growth in direct threats to people's safety in recent years and the rapid increase in fraud and identity theft has increased the awareness of security requirements in society and added urgency to the task of developing biometric-based person identification as a reliable alternative to conventional authentication methods.In this Chapter we describe various approaches to face recognition with focus on wavelet-based schemes and present their performance using a number of benchmark databases of face images and videos.These schemes include single-stream (i.e.those using single-subband representations of face) as well as multi-stream schemes (i.e.those based on fusing a number of wavelet subband representations of face).We shall also discuss the various factors and quality measures that influence the performance of face recognition schemes including extreme variation in lighting conditions and facial expressions together with measures to reduce the adverse impact of such variations.These discussions will lead to the introduction of new innovative adaptive face recognition schemes.We shall present arguments in support of the suitability of such schemes for implementation on mobile phones and PDA's. 7www.intechopen.
