Calibrated Uncertainty for Trustworthy Clinical Gait Analysis Using Probabilistic Multiview Markerless Motion Capture
Researchers have developed a probabilistic markerless motion capture method to improve the trustworthiness of clinical gait analysis. This approach quantifies epistemic uncertainty, allowing it to identify unreliable outputs without additional instrumentation. The model demonstrated reliable calibration with Expected Calibration Error (ECE) values generally below 0.1 for step and stride length, and bias-corrected gait kinematics. Errors for step and stride length were approximately 16 mm and 12 mm, respectively, with kinematic errors ranging from 1.5 to 3.8 degrees. AI
