This paper introduces a mathematical model that incorporates the pertinent optical and physiological properties of skin reflections with the objective to increase our understanding of the algorithmic principles behind remote photoplethysmography (rPPG). The model is used to explain the different choices that were made in existing rPPG methods for pulse extraction. The understanding that comes from the model can be used to design robust or application-specific rPPG solutions. We illustrate this…

Color-Distortion Filtering for Remote Photoplethysmography

A novel “Color-Distortion Filter” (CDF) that can be used as a common pre-processing step for arbitrary rPPG algorithms to increase their robustness, and the benchmark in challenging fitness recordings shows that CDF brings significant and consistent improvements to all benchmarked rP PG algorithms, and drives all multi-channel approaches to a similar high quality-level.

Improved motion robustness of remote-PPG by using the blood volume pulse signature

It is shown that the different absorption spectra of arterial blood and bloodless skin cause the variations to occur along a very specific vector in a normalized RGB-space, which can be determined for a given light spectrum and for given transfer characteristics of the optical filters in the camera.
