The accuracy of pulse rate estimation from the sequence of face images

摘要

The goal of this paper is to analyze the accuracy of pulse rate estimation from the sequence of face images. Simulated and real signals were used to evaluate two pulse rate estimators; one for frequency domain and the second one for time domain using the autocorrelation function. The results show that the mean difference between the reference measurements and estimated pulse rate values are about 2bpm. In the analysis of short signals the estimator working in time domain has better accuracy since it is not limited by spectral leakage observed in the analysis of spectrum for short length signals.
