An automated 2d marker tracking algorithm for kinematic assessment

Collecting and analyzing single view 2D videos could serve as a clinically feasible surrogate to assessing kinematics with 3D motion capture, which is typically used for laboratory research. The purpose of this study was to develop a novel algorithm that tracks markers in 2D videos, and to test the validity of quantifying sagittal plane foot kinematics during gait with a 2D video relative to with a 3D motion capture system.
