WebChronological age estimation is essential in the medical and forensic world because it is the biological profile of each individual. The purpose of this study is to present a chronological age estimation algorithm based on Photoplethysmography (PPG) signals. The algorithm is divided into four stages: preprocessing, feature extraction, classification, and estimation. … Web1.1 Background on photoplethysmography (PPG) Plethysmographs measure changes in volume. The only method to measure absolute changes in blood volume accurately in the extremities is by using chamber-plethysmography. The volume change can be converted into blood flow by using F = dV/dt. However, in some cases,
A photoplethysmogram (PPG) is an optically obtained plethysmogram that can be used to detect blood volume changes in the microvascular bed of tissue. A PPG is often obtained by using a pulse oximeter which illuminates the skin and measures changes in light absorption. A conventional pulse oximeter … See more While pulse oximeters are commonly used medical devices, the PPG derived from them is rarely displayed and is nominally only processed to determine heart rate. PPGs can be obtained from transmissive absorption (as at the … See more Conventional imaging While photoplethysmography commonly requires some form of contact with the human skin (e.g., ear, finger), remote photoplethysmography … See more Monitoring heart rate and cardiac cycle Because the skin is so richly perfused, it is relatively easy to detect the pulsatile component of the … See more • Heart rate monitor • Clitoral photoplethysmograph • Hemodynamics • Laser Doppler imaging See more WebAug 5, 2014 · The algorithm we developed was verified on PPG data segments recorded by simulation, laboratory-controlled and walking/stair-climbing experiments, respectively, and we compared several well-established MNA detection methods to our proposed algorithm. ...
