Figure files for "Understanding heterogeneous and anisotropic porous media based on geometric properties extracted from three-dimensional images"

There are three types of images: Segmented images of coral sample (D1-1), fractured rock (D2-1); Coral sample after filling holes (D1-2); Visualization results of ice crystals (D3-1, D3-2); Visualization results of coral sample heterogeneity and it derived simplified model (D1-3, D1-4).
