Heart Rate Measurement in the Presence of Noises

Heart rate profile related to exercise or other physical activities can be a crucial indicator of individual health according to recent researches. This makes heart rate measurement without interfering ongoing activity plays an important role in medical services and pervasive computing applications. However, there are challenges for wearable apparatuses to measure the heart rate in good accuracy and reliability: the lack of sophisticated signal processing capability and the generation of noises caused by physical activity. In this paper, a robust heart rate measuring algorithm is proposed. Several experiments are conducted to give evidence of the robustness and accuracy of the proposed algorithm
