Motion-robust continuous heart rate measurement

At least one machine-readable medium having instructions stored thereon that, in response to execution, cause a computing system to perform operations for estimating a continuous heart rate of a subject, the operations comprising:

• acquiring pulsatility data indicative of a cardiac cycle of the subject during sampling time tn, where n is an integer;
• acquiring motion data indicative of a motion of the subject while the pulsatility data is measured from the subject during the sampling time tn;
• performing frequency transformations on the pulsatility and motion data over discrete windows of a temporal length T to generate a set of windowed spectra, wherein the discrete windows are temporally overlapping and each temporally offset from one another;
• outputting heart rate values each corresponding to one of the windowed spectra using a processing pipeline including one or more neural networks trained to collectively output one of the heart rate values for each windowed spectra;
• and
• estimating the continuous heart rate for the sampling time tn based upon a set of the heart rate values associated with the sampling time tn from the discrete windows that are temporally overlapping.
