    Area of Science:

    • Computer Vision
    • Biometrics
    • Artificial Intelligence

    Background:

    • Gait recognition shows promise for remote person identification but struggles with real-world and outdoor datasets.
    • Existing indoor-focused gait recognition methods often lack generalizability and practical robustness.

    Purpose of the Study:

    • To conduct a comprehensive benchmark study focused on improving the practicality of gait recognition systems.
    • To address the limitations of current methods in real-world, outdoor scenarios.

    Main Methods:

    • Development of OpenGait, a flexible and efficient gait recognition platform.
    • In-depth ablation experiments using OpenGait to analyze recent gait recognition advancements.
    • Development of three novel baseline models: DeepGaitV2 (appearance-based), SkeletonGait (model-based), and SkeletonGait++ (multi-modal).

    Main Results:

    • Identification of previously overlooked insights and imperfections in existing gait recognition methods.
    • Development of DeepGaitV2, SkeletonGait, and SkeletonGait++ achieving state-of-the-art performance.
    • Demonstration of practical robustness and empirical power in the new baseline models.

    Conclusions:

    • The study provides new perspectives on deep gait modeling and the representational capacity of gait modalities.
    • The developed models offer significant improvements in practical gait recognition, especially for outdoor environments.
    • Future research should focus on key trends and challenges to enhance the practicality of gait recognition.
