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.

First claim

The invention claimed is:

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 skin-pixel-identifier that is operably coupled to the cropper and that identifies pixel values that are repres…
