Title: Face%20Image%20Recognition


1
Face Image Recognition
  • Face recognition technology works well with most
    of the shelf PC cameras, generally requiring
    320240 resolution at 35 frames per second.
  • Facial recognition software products range in
    price from US50 to over US1000, 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

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 300300 fingerprint
    image in a 2cm by 2cm area.
