The important physiological indicator heart rate (HR) says a lot about the person’s fitness and variation in this parameter can reveal information about their life style, stress levels or sleep quality. A study on bout of innovations and experimentations on heart rate estimation using the photoplethysmographic (PPG) signal is carried out in this paper. There are a number of signal processing algorithms that can be applied to the raw PPG signals from which we can have the heart rate measurement. But motion artifact (MA) comes into play when the subject is undergoing some type of motion and is the main factor that degrades the accuracy of this HR measurement. Most of the modern research in this area is mainly concerned on this MA reduction or attenuation to extract the actual HR. With the advance of computer and photonics technology, this contact-PPG based HR measurement could be extended to contactless imaging photoplethysmography (IPPG). So here we try to explore the concepts of all PPG based HR measurement.
