Abstract
A method and apparatus are provided for estimating the value of a physical parameter of biological tissue. The method comprises acquiring a colour image of the biological tissue from a single image capture device; extracting from the colour image at least two images in respective optical wavebands having a different spectral sensitivity from one another, whereby a given location in the biological tissue is present in each of the extracted images; providing a physical model of the optical properties of the biological tissue, wherein the optical properties of the biological tissue are sensitive to the value of said physical parameter; and estimating the value of the physical parameter at said given location based on an intensity value at that location for each extracted image. The estimating utilises the physical model of the optical properties of the biological tissue and the spectral sensitivity for each respective waveband.
