In the article authors presented digital measurement problem of the object on the 3D images of the microstructures. As a research material were used the micro tomography image of the probe C45 steel with WC-Co Al2O3 surface layer. Due to relatively low contrast between the surface layer and the root material, and lack of sharp edges, some of the methods for automatic threshold indication may give biased results. Following the initial selection of the many methods of automatic binarization, two of them, Yen and Triangle and one interactive method was selected to carry out comparative studies. Quantitative analysis included assessment of the layer thickness, number of detected objects and total volume of all detected objects.
