METHOD OF ESTIMATING DIFFUSION OF LIGHT

摘要

The invention relates to a method of estimating the amount of light diffused by a heterogeneous participant medium (10). In order to improve rendition whilst minimizing the necessary calculation times, the method comprises the steps of: - estimation of coefficients of projection in a function basis with the help of values representative of density for a set of points (13) of said medium that are situated along at least one direction of emission (110) of light by a light source (11), and - estimation of the amount of light diffused by said medium (10), according to at least one direction of diffusion (120) of the light, with the help of said estimated projection coefficients.
