A fast, window-less non-contact imaging photoplethysmography method allowed accurate measurement of heart rate with errors equivalent to state-of-the-art techniques but much faster computation.
A novel window-less imaging photoplethysmography method enables fast, real-time measurement of heart rate and heart rate variability with accuracy comparable to state-of-the-art techniques.

May enable real-time non-contact HR monitoring; hypothesis-generating and requires prospective validation before clinical use.
Imaging photoplethysmography (iPPG) allows non-contact, concomitant measurement and visualization of peripheral blood flow using just an RGB camera. Most iPPG methods require a window of temporal data and complex computation, this makes real-time measurement and spatial visualization impossible. We present a fast,“window-less”, non-contact imaging photoplethysmography method, based on a tissue-like model of the skin, that allows accurate measurement of heart rate and heart rate variability parameters. The error in heart rate estimates is equivalent to state-of-the-art techniques and computation is much faster.

McDuff et al. (2018) studied this question. Fast, window-less, non-contact imaging photoplethysmography method vs. State-of-the-art techniques was evaluated on Heart rate and heart rate variability parameters estimation error and computation speed. A fast, window-less non-contact imaging photoplethysmography method allowed accurate measurement of heart rate with errors equivalent to state-of-the-art techniques but much faster computation.
