Estimation of diffuse reflectance spectrum from RGB values by the synthesis of new colors for tissue measurements

A modified Wiener estimation method is presented for the accurate estimation of diffuse reflectance spectra from RGB values. In this method, the original RGB values are combined with a set of synthetic optical filters to generate another new three color values by using the system matrix. A modified...
