摘要
A method and device for estimating a porosity ratio of a sample of material from at least one gray-scale coded image. The method includes: evaluating an intermediate ratio of a sample for each value of a plurality of gray-scale threshold values lying between two determined limit values, the intermediate ratio being equal to a ratio of a number of pixels of the at least one image having a gray-scale value bounded by the threshold value to a total number of pixels of the at least one image; and estimating the porosity ratio of the sample by analyzing variations in the intermediate ratio as a function of the threshold value.
