Concluding Remarks and New Horizons in Skin Perfusion Studies
TL;DR: In this article, the authors summarized the historical development of camera-based photoplethysmography (PPG) and pointed at future technical directions, particularly at hybrid imaging in which RGB/NIR cameras may be combined with other frequency bands.
Patent
Optoelectronic blood flow measuring device for e.g. analyzing pulsatile perfusion phenomenon for cardiovascular diagnosis in human, has light sources radiating light of wavelengths lying specific nanometers apart from each other
TL;DR: In this article, a computer-controlled optrode (RMO) including four selective light sources (L1-LN) e.g. LED, and a light detector (D), where the sources radiate measured light of different wavelengths lying 300 nanometers apart from each other.

Determination of Hypertension Disease with Optimal Frequency Range of Short-Time Photopletismography Signals
TL;DR: In this article, a model for the detection of hypertension disease in individuals using the optimal frequency ranges of 2.4-5.7 Hz of short-time photopletesmography (PPG) signals was proposed.

Finger photoplethysmogram signal enhancement: Comparing performance between PCA and ICA methods
TL;DR: This paper compares the performance between two popular statistical signal processing tools, viz., principal component analysis (PCA) with fast independent component analysis (/ICA) in reduction of MA from finger pulse signal collected from 30 human volunteers and found that beat to beat correlation is higher in the PCA preprocessed data.
