This study introduces Gait Energy Image (GEI), a novel spatio-temporal representation for human gait recognition. GEI effectively identifies individuals by analyzing walking properties, offering a new method for biometric identification.

Area of Science:

  • Computer Vision
  • Biometrics
  • Pattern Recognition

Background:

  • Individual recognition by gait is a challenging biometric task.
  • Existing gait recognition methods often suffer from a lack of sufficient training data.

Purpose of the Study:

  • To propose a new spatio-temporal gait representation called Gait Energy Image (GEI).
  • To develop a novel approach for human recognition by combining real and synthetic gait templates to overcome data scarcity.

Main Methods:

  • GEI is computed directly from training silhouette sequences.
  • Synthetic templates are generated by simulating silhouette distortion.
  • Statistical methods are employed to learn effective features from both real and synthetic templates.

Main Results:

  • The proposed GEI representation is shown to be effective and efficient for gait recognition.
  • The combined approach using real and synthetic templates achieves highly competitive performance.

Conclusions:

  • GEI is a promising gait representation for individual recognition.
  • The proposed method effectively addresses the challenge of limited training data in gait recognition.
