Abstract
The present invention relates to a device, system and method for pulsatility detection. 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 a time-varying signal indicative of a periodic physiological phenomenon from a region of interest of said image data, a transformation unit () for transforming said time-varying signal into a spectral signal, a partitioning unit () for partitioning the spectral signal into at least an in-band sub-signal covering a first frequency range of said spectral signal and an out-band sub-signal covering a second frequency range of said spectral signal, wherein said first frequency range comprises at least a frequency range of the periodic physiological phenomenon, an analysis unit () for separately deriving an in-band measure from the in-band sub-signal and an out-band measure from the out-band sub-signal, the in-band measure and the out-band measure representing a descriptor, and a classifier () for classifying said region of interest as a pulsatile region of a living being or as a non-pulsatile region based on the descriptor.
