Abstract
The present invention relates to a device and method for processing physiological signals of a subject and in particular to a system for monitoring a (vascular) health parameter of a subject including such a device. The proposed device () comprises an input interface () for obtaining image data of a scene, said image data comprising a time sequence of image frames; an extraction unit () for extracting time-varying signals () indicative of cardiac-synchronous motion from said image data, wherein said time-varying signals () are motion signals indicative of a vascular micro-motion indicative of a vascular displacement waveform; a polarity determination () unit for determining a polarity of the time-varying signals, wherein the polarity corresponds to a phase of the time-varying signals; a combination unit () for combining time-varying depending on their polarity to obtain a combination signal; and an analysis unit () for determining a (vascular) health parameter based on the combination signal.
