Abstract

See full text

An apparatus includes a cropper operable to receive images and crop the images to exclude a border area, thus generating cropped images, a skin-pixel-identifier coupled to the cropper and that identifies pixel values that are representative of the skin in the cropped images, a first frequency filter coupled to the skin-pixel-identifier and that applies a frequency filter to output of the skin-pixel-identifier, a regional facial clusterial module coupled to the first filter and that applies spatial clustering to the output of the first filter, a second frequency filter operably coupled to the regional facial clusterial module and applied to the output of the regional facial clusterial module, a temporal-variation identifier coupled to the first filter and that identifies temporal variation of the output of the first filter, and a vital-sign generator coupled to the temporal-variation identifier that generates at least one vital sign from the temporal variation.
