Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

This seminar paper explores a novel approach to human recognition using gait analysis, a relatively new and increasingly popular area in biometrics. The paper aims to present a simple and effective solution to the problem of gait recognition by building upon existing research on the Silhouette Vector, a feature that describes the distance of boundary points from the centroid of a rotating silhouette. The paper's objective is to demonstrate the effectiveness of this method by integrating additional features based on the silhouette image, thereby enhancing the accuracy of the recognition system.

• Gait Recognition as a Biometric Approach
• The Silhouette Vector Feature
• Integration of Additional Features for Improved Accuracy
• Evaluation of the Recognition System Using Statistical Measures
• Potential for Future Research and Development
