Markerless Active Trunk Shape Modelling for Motion Tolerant Remote Respiratory Assessment

• dataset: https://data.bris.ac.uk/data/dataset/1tqzx39mzkw832msuvy3obktqi

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.
