Data post-processing including fixing labeling errors (left) and marker occlusions.
The three orange markers in the red circle represent unlabeled markers, and we manually assign correct labels to these markers in order to reconstruct the correct right-hand skeleton. The yellow marker in the green circle represents the occluded marker which causes a gap in the data trajectory (inside the green rectangle), and we make cubic interpolations to fill this gap.
