Beschreibung
This book includes Biometric systems, structure of Biometric systems, classifications of Biometrics,Fingerprint:characteristics,Fingerprint classifications and problems of Biometric systems. Different phases such as Preprocessing, Image Enhancement, Minutiae Extraction, Post processing and biometric template generation are discussed in this book. The book provides the survey report on the filtering techniques such as Average Filtering, Median Filtering and Adaptive Wiener Filtering techniques. It highlights a scheme to eliminate noise using Median filter. It specifically focuses on frequency domain enhancement with Log-Gabor filter and Fast Fourier Transformations. Minutiae extraction techniques and post processing phases are also discussed. New techniques namely Shift-Phase Transformation (SPT), Complex Conjugate-Phase Transformation (CCPT) and Reciprocated Magnitude and Complex Conjugate-Phase Transformation (RMCCPT)are proposed and discussed. They are designed to produce cancelable and irrevocable biometric fingerprint templates. The book furthermore presents experimental results and performance measures of the fingerprint template generation techniques.
