The focus of this book is on developing user interfaces that identify and verify legitimate users in real-time due to their biometric characteristics. Face and hand geometry are the biometric identifiers that are used in the applications. Application programs using these biometric identifiers are developed in unimodal and multimodal cases. In this book, six Java applications are developed to capture users' hand and face images in real-time, to enroll, to verify and identify them. All of the applications are designed as wizard applications and are built upon the same scenario. In the face recognition, Gabor jets are used to extract feature values of the face images. Matching the person is done according to the Gabor based feature vectors. In the hand recognition task, hand shape-based approach is applied on the hands. Hand segmentation, normalization and feature extraction are the important steps of this approach. Performance evaluation of the system is done by both empirical and observational methods.
