Device, system and method for skin detection
The present invention relates to a device, system and method for skin detection. To enable a reliable, accurate and fast detection the proposed device comprises an input interface (30) for obtaining image data of a scene, said image data comprising a time sequence of image frames, an extraction unit (31) for extracting a photoplethysmography (PPG) signal from a region of interest of said image data, a transformation unit (32) for transforming said PPG signal into a spectral signal, a sorting unit (33) for sorting said spectral signal to obtain a sorted spectral signal representing a descriptor, and a classifier (34) for classifying said region of interest as skin region of a living being or as non-skin region based on the descriptor.
