Methods of extracting feature from photoplethysmogram waveform for non-invasive diagnostic applications

Abstract

This paper presents a bibliographical survey of recently published research on different techniques for extracting features from photoplethysmograms (PPG). These techniques and approaches have been implemented to increase the accuracy of disease detection. Moreover, several aspects of PPG waveform analysis, including techniques for feature extraction, parameters involved, and performance comparisons, are discussed. This review will serve as a comparative study and reference for researches working on PPG waveform in healthcare applications.
