Smart healthcare is a new form of healthcare system that establishes better diagnostic tools and devices for improving the quality of life . To date , there are many health care devices that have been developed for measuring vital signs but most of them are of single subject assessment with limited parameter measurements , and inconvenient for continuous measurements monitoring due to their contact basis . Furthermore , the bulky size and pricey equipment might also be the barrier which hinder users from frequently monitoring their health status . |
As an alternative approach , this research aims to extract the vital signs through video image processing techniques using an ordinary RGB camera . Digital signal processing is applied to remove unwanted noises to extract a clean bio-signal . This research is very beneficial in simultaneously extracting multiple vital signs and promises high potential due to its non-contact basis , harmless and suitability for continuous monitoring . Besides , developing the techniques as a smartphone app would make it more convenient to operate and economical . |
