Frequency-Domain Methods for Biometric Recognition
28 03 2007Prof. Vijayakumar Bhagavatula and Dr. Marios Savvides, Carnegie Mellon University
Abstract
Identity recognition is important in many applications including access control and surveillance. Current approaches for identity recognition are based on passwords or PINs that can be lost, stolen or forgotten. Use of biometrics (e.g., face image, fingerprints, and iris image, etc.) for identity recognition is more attractive since biometrics are integral to a person. Recently, new correlation filter-based biometric recognition algorithms have been developed that work in the spatial frequency domain (i.e., the 2-D discrete Fourier transform of the images) and offer benefits such as shift-invariance, graceful degradation and closed-form expression. These frequency domain-based methods have performed very well in the face recognition grand challenge (FRGC) and the iris challenge evaluation (ICE). The goal of this tutorial is to present the underlying theory as well as the application of correlation filters for biometric recognition. In particular, three biometric modalities (namely face image, iris image and fingerprint) will be considered, although these techniques can be easily extended to other image-type biometric modalities. This course will review the needed basic concepts from linear algebra, signal processing, optimization and pattern recognition theory to help the attendees understand the advantages and limitations of correlation filters. This course will present the design of correlation filters and summarize the performance of the correlation filter-based approaches with publicly-available biometric data bases as well as in challenges such as the face recognition grand challenge (FRGC) and iris challenge evaluation (ICE).
