PPG Quality Algorithms
Algorithms to assess the quality of photoplethysmogram (PPG) signals.
Overview: PPG-quality contains several algorithms to assess the quality of photoplethysmogram (PPG) signals. This page provides an overview of these algorithms. Follow the links for further details on each one.
Accompanying tutorial: See this tutorial for an example of how to use the algorithms.

Description: The signal similarity is the correlation between the current pulse wave's shape and the previous pulse wave's shape. Before calculation, pulse waves are interpolated to a constant number of samples to account for handle pulse wave duration.
