PhysioMoCap: Motion Capture and Biomechanics Analysis for PhysioExperiment Objects

Provides motion capture, pose estimation, and biomechanical simulation analysis for PhysioExperiment objects. Includes I/O for C3D, Venus3D, GaitRec, OpenPose, DeepLabCut, MediaPipe, BVH, ASF/AMC, OpenSim, and generic CSV formats. Provides marker tracking (Hungarian algorithm), signal filtering, numerical differentiation, resampling, center of mass calculation, gait parameters, clinical statistics (ICC, SEM, MDC, Bland-Altman), movement phase segmentation, dynamic time warping, movement normalization, functional PCA, force-plate kinetics (GRF filtering, COP, loading rate, impulse), planar inverse dynamics (joint moments/power), EMG integration (rectification, RMS envelope, MVC normalization), gait/running/jump task schemas, OpenSim workflow integration, and biomechanics-specific visualization.
