MATLAB code for: "Photoplethysmography Acceleration Indices as Digital Biomarkers of Cardiometabolic Health"

The LOTUS is a GUI primarily built to read, compile, and analyse raw Empatica EmbracePlus data over user-defined periods of time. Fragmented 'chunks' of raw timeseries data output by Empatica (i.e., EDA, BVP, systolic peaks, temperature, accelerometer, and event tags) can be selectively reconstituted as continuous timeseries for further processing.

Heartbeat measurement with Photoplethysmogram (PPG) using Fast Fourier transform

This repository contains heart rate analysis including time and frequency domain. The extracting algorithms are Eulerian Video Magnification. (not included)

Code to estimate HR from PPG signals using Subspace Decomposition and Kalman filter for the dataset of 22 PPG recordings provided for the 2015 IEEE Signal Processing Cup (SP Cup) competition. The traces are stored in folder 'DATABASE'. Please cite this publication when referencing this material: "Measuring Heart Rate During Physical Exercise by …
