Algorithm for post-processing of tomography images to calculate the dimension-geometric features of porous structures

An algorithm for post-processing of the grayscale 3D computed tomography (CT) images porous structures with automatic selection filtering parameters is proposed. The determination carried out on a representative part image under analysis. A criterion search optimal based count "levitating stone" voxels described. stages CT and its binarization are performed sequentially. Bilateral anisotropic diffuse implemented; Otsu method unbalanced classes chosen binarization. Verification proposed was model data. To create structures, we used our generator, which implements function generation. Results real containing noise reconstruction artifacts by discussed.
