Figure 5

Comparison of arm-asymmetry scores between automatic method and ground truth in a video segment containing participant number 1. The cyan line represents normalized results from our method, while the red line represents the ground truth (GT) of the normalized arm differences. See [28] for more information on arm-asymmetry calculations and analysis. The normalized color scale visually displays the angle difference between the right and left forearms, where symmetric arm positions have similar overlaying colors.
