Extending Kubelka-Munk’s Theory with Lateral Light Scattering
نویسندگان
چکیده
Due to its simplicity, the theory of KUBELKA-MUNK [1] has found a wide acceptance for modeling the optical properties of light scattering materials. However, the concept is not explicitly adapted to predict halftone prints on paper. In this respect, a recent improvement was given by BERG [2]. Our approach is an extension of BERG’s model in order to reduce the gap between the mathematical description of the paper’s point spread function and the experimental results of simple reflectance measurements.

A Random Walk Approach for Light Scattering in Material
Seeing means perceiving light from an external source which was scattered in a material medium and reemitted toward the observer’s eye. Thereby colors are the result of wavelength dependent absorption processes. The physical basis of color as molecular or atomic phenomenon is state-of-the-art in science, both in experimental and in theoretical respect. But to the authors knowledge, the deriving...
متن کاملRevised Kubelka-Munk theory. III. A general theory of light propagation in scattering and absorptive media.
A generally applicable theoretical model describing light propagating through turbid media is proposed. The theory is a generalization of the revised Kubelka-Munk theory, extending its applicability to accommodate a wider range of absorption influences. A general expression for a factor taking into account the effect of scattering on the total photon path traversed in a turbid medium is derived...
متن کاملExamination of the revised Kubelka-Munk theory: considerations of modeling strategies.
The revised Kubelka-Munk theory is examined theoretically and experimentally. Systems of dyed paper sheets are simulated, and the results are compared with other models. The results show that the revised Kubelka-Munk model yields significant errors in predicted dye-paper mixture reflectances, and is not self-consistent. The absorption is noticeably overestimated. Theoretical arguments show that...
متن کاملEmpirical relationship between Kubelka-Munk and radiative transfer coefficients for extracting optical parameters of tissues in diffusive and nondiffusive regimes.
Kubelka–Munk (K-M) theory is a phenomenological light transport theory that provides analytical expressions for reflectance and transmittance of diffusive substrates such as tissues. Many authors have derived relations between coefficients of K-M theory and that of the more fundamental radiative transfer equations. These relations are valid only in diffusive light transport regime where scatter...
متن کاملA Comparison between Kubelka-Munk and Geometric Models for Prediction of Reflectance Factor of Transparent Fibers
The reflectance factors of transparent fibers, free delustering agent, are predicted by geometric as well as Kubelka-Munk models. Transparent fibers are simulated by a net of glass capillary tubes containing different solutions of dyestuffs. Based on the results, prediction of the reflectance factor of capillary net by geometric model is relatively better than those obtained from Kubelka-Munk...
