NON-TOUCH OPTICAL DETECTION OF BIOLOGICAL VITAL SIGNS
First Claim
1. An apparatus of variation amplification to communicate a biological vital sign, the apparatus comprising:
- a microprocessor that is programmed to execute;
a cropper that is operable to receive at least two images and that is operable to crop each of the images to exclude a border area of the images, generating at least two cropped images;
a spatial bandpass filter that is operably coupled to the cropper and that processes output of the cropper;
a regional facial clusterial module that is operably coupled to the spatial bandpass filter and that applies spatial clustering to output of the spatial bandpass filter;
a temporal bandpass filter that is operably coupled to the regional facial clusterial module and that is applied to output of the regional facial clusterial module;
a temporal-variation identifier that is operably coupled to the temporal bandpass filter and that identifies a temporal variation in output of the temporal bandpass filter;
a vital-sign generator that is operably coupled to the temporal-variation identifier that generates the biological 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 biological vital sign.

Abstract
A microprocessor is programmed to execute a spatial bandpass filter that is operable to apply spatial bandpass filtering to a plurality of images, a regional facial clusterial module that is operably coupled to the spatial bandpass filter and that applies spatial clustering to output of the spatial bandpass filter, a temporal bandpass filter that is operably coupled to the regional facial clusterial module and that is applied to output of the regional facial clusterial module, a temporal-variation identifier that is operably coupled to the temporal bandpass filter and that identifies a temporal variation of the output of the temporal bandpass filter and a vital-sign generator that is operably coupled to the temporal-variation identifier that generates a biological vital sign from the temporal variation.
