Key result
Independent component analysis pre-processing of imaging photoplethysmography improved frequency domain descriptors of heart rate variability, with a mean absolute error of 3.812 ms for NN intervals.
Why the study?
Does independent component analysis (ICA) pre-processing improve the accuracy of heart rate and heart rate variability assessment from imaging photoplethysmography (iPPG) in healthy volunteers?
Does independent component analysis (ICA) pre-processing improve the accuracy of heart rate and heart rate variability assessment from imaging photoplethysmography (iPPG) in healthy volunteers?
Independent component analysis (ICA) pre-processing can effectively improve the accuracy of heart rate and heart rate variability assessment from video-based imaging photoplethysmography.

ICA pre-processing may improve single-channel iPPG-derived HR/HRV; leaves open prospective validation before clinical use.
Favilla et al. (2018) studied Healthy volunteers. Independent component analysis (ICA) pre-processing of imaging photoplethysmography vs. iPPG without ICA pre-processing and ECG was evaluated on Heart rate and heart rate variability (mean absolute error). Independent component analysis pre-processing of imaging photoplethysmography improved frequency domain descriptors of heart rate variability, with a mean absolute error of 3.812 ms for NN intervals.
