Summary

SCGait, a novel gait recognition method, enables person identification and tracking for legged robots without requiring active cooperation from the identified individual. Published on April 21, 2026, SCGait achieves a mean test accuracy of 82.2% on three subsets of the CASIA-B dataset. The method integrates a symmetry-encoding technique and a pseudo-Centroid loss function, demonstrating good generalization ability. When combined with Yolo, SCGait forms a person identification-tracking system that performs effectively in multi-person scenarios for companion and industrial patrol robots, yielding an identification accuracy of 91.8% and a frame rate of 36 FPS in test videos. The code for SCGait is publicly available on GitHub.

Key takeaway

For Computer Vision Engineers developing autonomous robot systems, SCGait offers a robust, passive person identification solution. Its high accuracy and real-time performance, especially when integrated with Yolo, make it suitable for applications like companion robots or industrial patrol. Consider implementing SCGait to enhance robot autonomy and user interaction without relying on active user input.
