Claim Text:
1. An apparatus of motion amplification to communicate biological vital signs, the apparatus comprising: a cropper module that is operable to receive at least two images and crop the image to exclude a border area of the images, generating at least two cropped images; a skin-pixel-identification module that is operably coupled to the cropper module and that identifies pixel values that are representative of the skin in at least two cropped images; a first frequency filter module that is operably coupled to the skin-pixel-identifier and that includes a first frequency filter and that applies the first frequency filter to output of the skin-pixel-identifier; a regional facial clusterial module that is operably coupled to the first frequency filter module and that applies spatial clustering to the output of the first frequency filter module; a second frequency filter module that is operably coupled to the regional facial clusterial module and that includes a second frequency filter and that applies the second frequency filter to output of the regional facial clusterial module, generating a temporal variation; a vital-sign generator that is operably coupled to the second frequency filter module that generates at least one vital sign from the temporal variation; and a display device that is operably coupled to the vital-sign generator that is operable to display the at least one vital sign.
