Abstract: The invention relates to a method for determining the color of a cosmetic product on a skin model, the method including steps to: - for a plurality of wavelengths, supply experimental points giving diffusion and/or absorption values for several mixes of a given concentration of one pigment in another pigment, each mix corresponding to different given concentrations, and - use a physicochemical model capable of predicting interactions between pigments passing through experimental points to obtain the curve giving the diffusion and/or absorption for each wavelength as a function of the given concentration of pigment in the mix of pigments considered.

Abstract: The present invention relates to a method for characterizing eyelashes or eyebrows which is implemented by computer and comprises the following steps, which are directed toward: - receiving data corresponding to a set of pixels in a close-up image of a body area comprising a plurality of eyelashes, preferably the entirety of a row of eyelashes or of an eyebrow, to be characterized; - applying at least one step of computer vision so as to obtain, on the basis of the image data received, a numerical evaluation of at least one characteristic numerical parameter from among, notably, the number of fibers, an average length of the fibers, an average thickness of the fibers, and a curvature of the fibers.
