Biometrics

• Authentication based on the physiological or
  behavioral characteristics of people
• It is a pattern recognition system at
  establishes a persons identity by comparison of
  data .
• Its authentication is "automatic", "real-time",
  "non-forensic" subset of the broader field of
  human identification.

Examples of Biometrics

• Fingerprint
• Handwritten signature
• Facial recognition
• Speech recognition
• Gait recognition

What is Gait recognition

• It aims to discriminate individuals by the way
  they walk
• It is unobtrusive.
• It depends on how the silhouette shape of an
  individual changes over time in an image sequence

FEATURE EXTRACTION

• Silhouette Representation
• 2D silhouettes are changed into an associated
  sequence of 1D signals
• di((xi-xc)2(yi-yc)2)1/2
