non-stationary porous media

This dataset introduces a two-dimensional slice dataset of non-stationary porous media. Each group consists of 128 data slices with a resolution of 128×128, and there are 11 groups in total. The dataset mainly includes asphalt data and tight sandstone materials.
Another compressed package contains images of **stationary porous media**. Similar to the non-stationary porous media mentioned above, it includes multiple groups of data. Meanwhile, it covers a **wider range of porosity** and has more applications. Generally, the experimental performance is relatively better with higher porosity.
