NON-TOUCH OPTICAL DETECTION OF VITAL SIGNS FROM AMPLIFIED VISUAL VARIATIONS
First Claim
Patent Images
1. An apparatus of motion amplification to communicate biological vital signs, the apparatus comprising:
- a skin-pixel-identifier that identifies pixel values that are representative of the skin in at least two images;
a spatial bandpass filter that is operably coupled to the skin-pixel-identifier and that processes output of the skin-pixel-identifier;
a regional facial clusterial module that is operably coupled to the spatial bandpass filter and that applies spatial clustering to the output of the spatial bandpass filter;
a temporal bandpass filter that is operably 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 temporal variation of the output of the temporal bandpass filter;
a vital-sign generator that is operably coupled to the temporal-variation identifier 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.

Abstract
A microprocessor is operably coupled to a camera from which patient vital signs are determined. A temporal-variation-amplifier of at least two images is operable to generate a temporal variation, a vital-sign generator is operable to generate at least one vital sign from the temporal variation and a display device is operable to display the at least one vital sign.
