Gait Recognition

By Arshiya Khan

Biometrics Authentication based on the physiological

or behavioral characteristics of people It is a pattern recognition system at

establishes a person’s identity by comparison of data .

It’s authentication is "automatic", "real-time", "non-forensic" subset of the broader field of human identification.

Classifications Biometric systems:o Verification o Identification Biometric devices:o Positive Identification o Negative 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

Gait Recognition Algorithm

Human Detection and Tracking

FEATURE EXTRACTION Silhouette

Representation 2D silhouettes are

changed into an associated sequence of 1D signals

di=((xi-xc)2+(yi-yc)2)1/2

RECOGNITION

CONCLUSION Subject to the effects of different

types of clothes. Lack of generality of viewing

angles.
