Background:

Distinguishing abnormal gait patterns from normal ones is crucial for diagnosing neurological and musculoskeletal conditions.
Current methods often require extensive feature engineering or large labeled datasets, limiting their practical application.

Purpose of the Study:

To develop an automated, user-independent method for real-time anomaly gait detection using silhouette images.
To enable rapid deployment in diverse application scenarios without prior subject-specific gait analysis.

Main Methods:

A novel representation, the full gait energy image (F-GEI), was developed for feature extraction from gait silhouettes.
A semisupervised clustering algorithm was employed for binary classification to detect gait anomalies.
The method requires minimal prior data and no user parameter tuning for deployment.

Main Results:

The proposed method demonstrated effectiveness and efficiency in gait anomaly detection.
Performance was evaluated against state-of-the-art techniques on a human gaits dataset.
Results indicated high accuracy, robustness, and computational efficiency.

Conclusions:

The developed automatic computer method provides a fast and simple solution for anomaly gait detection.
The F-GEI representation and semisupervised approach allow for effective detection with limited data.
This technique holds promise for practical applications in healthcare and security.
