PCA/LDA Applications in Biometrics

Abstract

In this chapter, we show some PCA/LDA applications in biometrics. Based on the introductions to both PCA and LDA mentioned in Chapters II and III, their simple descriptions are given first. Then, we indicate a significant application in face recognition. The next sections discuss palmprint identification and gait verification, respectively. For other applications, ear biometrics, speaker identification, iris recognition and signature verification are respectively described. At the end of this chapter, we point out a brief but useful summary.
