This study introduces a new gait recognition system that combines spatial and temporal features for improved accuracy. The method enhances biometric identification by reducing data complexity and optimizing feature distinctiveness.

Area of Science:

  • Biometrics
  • Computer Vision
  • Pattern Recognition

Background:

  • Gait recognition is a challenging biometric identification method.
  • Existing methods often struggle with accuracy and data dimensionality.
  • Integrating spatial and temporal information can enhance gait analysis.

Purpose of the Study:

  • To develop a robust gait recognition system using extended template features.
  • To improve accuracy and reduce data dimensionality in gait sequences.
  • To optimize class separability for enhanced biometric identification.

Main Methods:

  • A statistical approach for feature extraction from spatial and temporal templates.
  • Dimensionality reduction via template extraction and Principal Component Analysis (PCA).
