Cervical Pulse Wave Extraction Based On Video Motion Amplification

In the development of computer aided diagnosis (CAD), there are many instruments for pulse signal acquisition. Traditional contact pulse wave collector is inconvenient and depends on complex electronic equipment. Based on Euler video magnification algorithm (EVM), a non-contact pulse wave lifting method based on video action amplification is proposed. The method uses only one digital camera to photograph the pulse in the neck position for pulse wave acquisition. Compared with the method the acquisition rate is higher in other non-contact ways.
