The kubelka–munk function
Web1 Oct 2004 · A, Optics, image science, and vision. Using a statistical analysis of light propagation in media, we propose a revision to Kubelka-Munk (K-M) theory by taking into account the effect of scattering on the path length of light propagation (path variation). This leads to new relationships between the K-M scattering S and absorbing K coefficients ... Web1 Jan 1996 · Notwithstanding that the Kubelka–Munk function [F(R)] is the theoretically preffered treatment, relative to log 1/r, for reflectance data, it has found little favour with …
