Markerless Active Trunk Shape Modelling for Motion Tolerant Remote Respiratory Assessment

What background they describe?

Both tests start with a few cycles of normal breathing, called tidal volume, followed by a maximal inhalation–exhalation, called main effort.
Spirometer: Difficult for anyone to use. Recalibrated. Expensive.
when a single depth sensor is used, decoupling trunk motion and chest-surface respiratory motion would be potentially impossible.

What is the evaluation metric?

$NL_2$ : Normalized L2 error,
$FRD$ : Fréchet distance,
$DTW$ : Dynamic Time Warping distance,
$R^2$ : Coefficient of determination correlation.
