A method of estimating the relative amounts of the two materials in a surface region of a mixture

摘要

Method of estimating the relative amounts of the two materials in a surface region of a mixture, and a corresponding device.Consists of: a) selecting the elements of Video Image signals from a Predetermined area of the surface of the mixture; (b) generating a histogram that is based on the total number of signals of the selected element of equal Light Intensity; and (c) to identify the areas most By The histogram generated for each material.It consists of a video camera (46); Elements (52) that generate a Greater range of Digital Image Element signals Representative of the received light from points on the surface of the mixture.
