Now-a-days, as everyone gives priority to their health vital signs estimation system plays a major role in monitoring the health and preventing from diseases. Heart rate (HR) and respiration rate (RR), also referred to as breath rate (BR), are vital indicators that must not be disregarded. Many methods have been proposed to identify these critical indicators. There are two primary categories of methods for measuring HR and BR: contact methods and non-contact approaches. Due to their excellent accuracy, contact methods—as the conventional techniques—are the most commonly used methods for measuring signs. An electrocardiogram (ECG) or photoplethysmography (PPG) is usually used as the most common method of contact. One of the most commonly used methods for obtaining an ECG signal is to place adhesive gel electrodes on a person’s chest or limbs in order to obtain an ECG signal with a significant amount of useful information about vital signs. As an optical technique, PPG is capable of detecting changes in the detected light intensity (i.e., variations in Blood Volume Pulse) in the microvascular bed of tissue. In the meanwhile, the BVP modifications may be used to provide useful information on the circulatory system and estimate BR and HR. Because transmitted light is easily recognized, a PPG sensor is usually placed on the fingertip to effectively monitor fluctuations in blood flow. As a result, PPG has become more well-liked as a contact-based technique in recent years. Nevertheless, because users must typically wear devices that require skin contact, these contact techniques may cause irritation and distress. As such, this endeavor proposes a PPG-based real-time technique for the contactless computation of HR and BR.
