Patent ID: 8792948

Claim:
An image processing system for obtaining biophysical information about a mammalian subject, said image processing system comprising: an image receiving unit for receiving a video electronic color image of a first tissue of the mammalian subject, the electronic color image comprising spatial temporal per pixel information for a color space of a first visible color, spatial temporal per pixel information for a color space of a second visible color and spatial temporal per pixel information for a color space of a third visible color, the electronic color image derived from light reflected from and/or traversing the first tissue, the light incident from a continuous or discontinuous, filtered or unfiltered, natural or artificial, light source and having a wavelength between near UV and near IR; and an image processing unit for electronically processing said image by transforming per pixel information for the first, second and third visible colors to transformed per pixel information for the first, second and third visible colors, determining values of meta-parameters by equating ratios of the transformed per pixel information for the first, second and third visible colors to a pre-defined function of meta-parameters and then solving for the values of the meta-parameters under mathematical constraints, to provide the biophysical information, the ratios are of spatial temporal per pixel information for at least one of the visible colors to said information for at least another of the visible colors, the image processing system adapted to obtain the biophysical information whether the incident light incident on the first tissue from the light source is filtered or unfiltered, continuous or discontinuous, of a natural light source or of an artificial light source.
