CardiacWave

The experiments show that the CardiacWave-induced ECG measures have a high positive correlation with the heart activity ground truth (i.e., measurements from a medical-grade instrument), indicating that CaridacWave offers high-fidelity and integral heart clinical characteristics.

Evaluation of a Low-Cost and Accessible Approach for Noninvasive Real-Time Blood Oxygen Saturation Measurement Using Video Images

Oxygen is an essential element for human survival, as it is the primary “fuel” for cells in our body. Thus, maintaining a safe level of oxygen in the blood-stream is crucial. Medical professionals…

On the Analysis of Fingertip Photoplethysmogram Signals

Different types of artifact added to PPG signal, characteristic features of PPG waveform, and existing indexes to evaluate for diagnoses are discussed.

Non-contact detection of oxygen saturation based on visible light imaging device using ambient light.

This is the first demonstration of an accurate video-based method for non-contact oxygen saturation measurements by using ambient light with their respective visible wavelength of 660nm and 520nm which is free from interference of the light in other bands.

Accurate measurement of the pulse wave delay with imaging photoplethysmography.

It is found that signal disturbances originate mainly from the stochastically enhanced dichroic notch caused by endogenous cardiovascular mechanisms, with smaller contribution of the motion artefacts.

Wearable Photoplethysmographic Sensors—Past and Present

This review presents the history of PPG and recent developments in wearable pulse rate sensors with green LEDs, and the application of Wearable pulse rate monitors is discussed.

Remote plethysmographic imaging using ambient light.

Plethysmographic signals were measured remotely (> 1m) using ambient light and a simple consumer level digital camera in movie mode. Heart and respiration rates could be quantified up to several…

Long Short-Term Memory

A novel, efficient, gradient based method called long short-term memory (LSTM) is introduced, which can learn to bridge minimal time lags in excess of 1000 discrete-time steps by enforcing constant error flow through constant error carousels within special units.
