1 Face Image Recognition Face recognition technology works well with most of the shelf PC cameras, generally requiring 320*240 resolution at 3~5 frames per second. Facial recognition software products range in price from US$50 to over US$1000, making one of the cheaper biometric technologies. Four primary methods used to identify or verify users by means of facial features, including eigenface, PCA, 2D-PCA, LDA, 2D-LDA, wavelet analysis, neural network, and ad hoc methods. Singular Value Decomposition and Pattern Recognition. Fast Fourier Transform and Wavelet Analysis  

8 Fingerprint Image Verification/Identification Each fingerprint is a map of ridges and valleys in the epidermis layer of the skin. The ridge and valley structures from unique geometric patterns. A minutiae pattern consisting of ridge endings and bifurcations is unique to each fingerprint. Most of the contemporary automated fingerprint identification and verification systems (AFIS) are minutiae pattern matching systems. A modern AFIS is composed of 5 primary modules: (1) Image Enhancement, (2) Image segmentation and Thinning, (3) Minutiae Points Extraction, (4) Core and Delta Localization, and (5) Point Pattern Matching. A fingerprint forum provided 5 sets of small databases for researchers to evaluate their identification/verification software. SecuGen EyeD and Veridicom are two leading companies selling both commercial fingerprint identification/verification systems and sensors with resolution 500dpi. Veridicom FPS110 fingerprint reader sensed a 300*300 fingerprint image in a 2cm by 2cm area.
