• Visual sensory system has attracted much interest in medical research due to the non-contact characteristic. Heart and breath rate are usually used as the primary indicator of the subject health status. Conventional heart and breath rate monitoring that is attached to the body is practically difficult to apply under certain conditions such as active babies, patients with burns or skin healing, and when free movement is needed. Therefore, in this paper, visual-based heart and breath rate monitoring system is developed by using a standard 30-fps camera as the primary sensor. Skin color and motion are magnified, followed by capturing region-of-interest, normalization, and filtering to get the respective heart and breath signals. Skin color is used due to blood flow activity during the cardiac cycle. Color and motion magnification is employed to strengthen changes in the information of video because signals from non-contact measurements have a low amplitude. Results from 28 subjects provided good acceptance level of 95% compared to the contact-based sensor, which is used as a validation tool.
