Towards Markerless Motion Estimation of Human Functional Upper Extremity Movement.

Markerless motion capture of human movement is a potentially useful approach for providing movement scientists and rehabilitation specialists with a portable and low-cost method for measuring functional upper extremity movement. This is in contrast with optical and inertial motion capture systems, which often require specialized equipment and expertise to use. Existing methods for markerless motion capture have focused on inferring 2D or 3D keypoints on the body and estimating volumetric representations, both using RGB-D.
