摘要
A process for technically measuring the texture of the surface of the human skin by the recording, reproduction and analysis of image data in which grey-scale images of the skin or a print of the skin surface (replica) are made under targeted lighting of the skin or replica at a predetermined angle of illumination, mathematical characteristics of the grey-scale distribution are found via digital image processing and a) images of a plane structure of differing contrast are also produced and characteristics are found via the grey-scale transitions and/or b) the run lengths of a grey-scale value and analysed with reference to their standard distribution and distribution functions and significant deviations.
