APPARATUS OF NON-TOUCH OPTICAL DETECTION OF VITAL SIGNS OF REDUCED IMAGES FROM SPATIAL AND TEMPORAL FILTERS
First Claim
Patent Images
1. An apparatus of motion amplification to communicate biological vital signs, the apparatus comprising:
- a cropper that is operable to receive at least two images and operable to crop the images to exclude a border area of the images, generating at least two cropped images;
a temporal-variation-amplifier of the at least two cropped images that is operable to generate a temporal variation;
a vital-sign generator that is operably coupled to the temporal-variation-amplifier that is operable to generate 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 of images from the camera is generated and amplified from which the patient vital sign, such as heart rate or respiratory rate, can be determined and displayed or stored.

11. An apparatus of motion amplification to communicate biological vital signs, the apparatus comprising:
-
a cropper that is operable to receive at least two images and operable to crop the images to exclude a border area of the images, generating at least two cropped images; a spatial bandpass filter that applies a frequency filter to at least two cropped 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 temporal variation of 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. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
