A Noncontact Measurement of Cardiac Pulse Based on PhotoPlethysmoGraphy

Heart rate measurement is important for monitoring people’s phys‐ iological and body state. In this paper, a heart rate measurement methodology based on PhotoPlethysmoGraphy (PPG) signal is proposed. Human face positions are detected and tracked in real time by using facial color videos taken from cameras by non-contact shooting. Signals containing pulse components are extracted from images of ...

Noncontact simultaneous dual wavelength photoplethysmography: a further step toward noncontact pulse oximetry.

We present a camera-based device capable of capturing two photoplethysmographic (PPG) signals at two different wavelengths simultaneously, in a remote noncontact manner. The system comprises a complementary metal-oxide semiconductor camera and dual wavelength array of light emitting diodes (760 and 880 nm). By alternately illuminating a region of tissue with each wavelength of light, and detect...

Motion-compensated noncontact imaging photoplethysmography to monitor cardiorespiratory status during exercise.

With the advance of computer and photonics technology, imaging photoplethysmography [(PPG), iPPG] can provide comfortable and comprehensive assessment over a wide range of anatomical locations. However, motion artifact is a major drawback in current iPPG systems, particularly in the context of clinical assessment. To overcome this issue, a new artifact-reduction method consisting of planar moti...

Pulse Transit Time Variability versus Heart Rate Variability during Decreases in the Amplitude fluctuations of Photoplethysmography signal

An analysis of the pulse transit time variability (PTTV) and HRV during decreases in the amplitude fluctuations of photoplethysmography (DAP) events, and their relationship with sleep apnea events is presented. 268 selected DAP events were extracted from complete night polysomnography recordings from 21 children and classified in 5 groups depending on oxygen saturation and respiratory behaviour...

Comment on 'Photoplethysmography sampling frequency: pilot assessment of how low can we go to analyze pulse rate variability with reliability?'

Accurate pulse rate detection is essential for reliable pulse rate variability analysis. On the other hand, minimizing the sampling frequency is essential to reduce the amount of data and computational needs, and consequently the power consumption of mobile/wearable devices, extending their operating hours. Determining the variability of physiological parameters needs a new paradigm since there...
