1. A method for assessing vasculature of tissue comprising: preprocessing hyperspectral information; building a visual image; defining a region of interest in tissue; decomposing a spectra for each pixel into several components; determining three planes for an RGB pseudo-color image; determining a sharpness factor plane; converting the RGB pseudo-color image to a hue-saturation-value/intensity image; adjusting the hue-saturation-value/intensity image plane with the sharpness factor plane; converting the hue-saturation-value/intensity image back to the RGB pseudo-color image; displaying the region of interest in pseudo-colors; and characterizing a metabolic state of the tissue of interest.
