Heart rate is an important sign of fetal health, yet few technologies exist to easily and inexpensively track fetal heart rates outside of doctors' offices. This can create risks for pregnancies in ...

Abstract: Digital signal processing is widely employed in digital multi-channel pulse height analyzers. However, achieving high-resolution high-throughput spectroscopy at high count rates remains a ...

Abstract: Despite the recent advances in remote heart rate measurement, most improvements primarily focus on recovering the rPPG signal, often overlooking the inherent challenges of estimating heart ...
