Abstract
An in situ optical oyster heart rate sensor generates
signals requiring frequency estimation with properties different
to human ECG and speech signals. We discuss the method
of signal generation and highlight a number of these signal
properties. An optimal heart rate estimation approach was
identified by application of a variety of frequency estimation
techniques and comparing results to manually acquired values.
Although a machine learning approach achieved the best
performance, accurately estimating 96.8% of the heart rates
correctly, a median filtered autocorrelation approach achieved
93.7% with significantly less computational requirement.
A method for estimating heart rate variation is also presented.
