Algorithm for Porous Media Reconstruction

Hello there,

I am meeting a problem on how to reconstruct a 3D geometry using a single 2D image. I've read some papers on this issue and found that methods such as autocorrelation were used to generate 2D slices based on a single 2D image and then generate the 3D porous media. However, I don't know how to write code for this issue in Matlab. Is there a simple code that can show me how to program this issue in Matlab? By the way, I've searched it in File exchange but cannot find this kind of code.

I reaaally appreciate if anyone can do me a favor.

The raw 2D image was shown as follows.

Many thanks,

Rick
