The RCF (retrospective collaborative filtering) algorithm uses time-frequency analysis to enhance the ECG data in real-time. The filtering result is consistent with FDA guidelines, and has been verified by Cardiologists, providing developers with a hassle-free way of starting their biomedical wearables product cycle.
