Human heart rate is a critical sign of people's physiological status and one of the most essential physiological markers. Depending on the patient's condition, the heartbeat can be monitored in a variety of methods, including contact basis, such as utilizing various devices or manually monitoring the pulse rate. We'd like to develop a non-contact gadget for measuring heart rate. Non-contact-based approaches are gaining popularity because they have the potential to address some of the disadvantages of contact-based techniques, especially in the therapeutic setting. We propose a method that detects the human face as an input and produces the pulse rate as an output. It will concentrate on two facial subregions: the forehead and the nose-mouth area. After the unstable characteristics have been removed, temporal filtering is used to isolate the frequencies of interest. The cardiovascular pulse signal is then separated from extraneous noise induced by respiration, vestibular activity, and other changes in face expression using four-component analysis methods. After that, each component derived from one of the four component selection procedures is subjected to the suggested peak detection approach. This will allow the position of peaks in each component to be determined. The proposed automatic components selection technique is used to choose the best component for calculating the heartbeat. This non-contact-based system will help in times where we are focusing on automating everything so as to make it contactless. This non-contact-based heart rate detection system will help in measuring the pulse rate without the use of expensive instruments.
