心率通常使用心电图（ECG）来测量，这需要患者佩戴具有粘性凝胶贴片的胸带，该粘性凝胶贴片可能是磨蚀性的并且使用户感到不舒服。还可以使用可以佩戴在指尖上的脉搏血氧饱和度传感器来监测心率。这些方法不便于长期使用。除了不适之外，这些方法在新生儿或老年人的情况下不是优选的，因为他们的皮肤非常脆弱。使用非接触式方法测量心率对于定期非侵入式监测可能是有益的，并且在监测家中的人时可能具有很大的价值。因此，本文提出了一种非接触式的，创新的心率监测技术，测量一个人的心率使用低成本的摄像机。该方法使用独特的技术分析RGB图像的绿色通道。瞬时心率的测量误差仅为2.07%，这是相当有前途的。
Heart rate is typically measured using an electrocardiogram (ECG), which requires patients to wear chest straps with adhesive gel patches that can be abrasive and become uncomfortable for the user. Heart rate may also be monitored using pulse oximetry sensors that may be worn on the fingertip. These methods become inconvenient for long-term usages. Besides the discomfort, these methods are not preferred in the case of newborn or elderly people as their skins are very fragile. Measuring heart rate using a noncontact method could be beneficial for regular non-obtrusive monitoring and may have great value in monitoring a person at home. Therefore, this paper presents a non-contact, innovative heart rate monitoring technique that measures a person's heart rate using a low-cost video camera. This method analyzes the green channel of the RGB images using a unique technique. The error in the measurement of instantaneous heart rate is of 2.07% only, which is quite promising.
