The code is separated into two sections: Geometric method and ML method The ML method can be found here. This code builds onto code from the SP-GAN paper by Li et al.
Due to privacy laws concerning dentistry shape material, we cannot share the original data here. Please email [email protected] for data.
You can download the code from this github page for the geometric method. Refer here for the GAN-Based method.
git clone https://github.com/ImaneChafi/C.B.GEN.git
The code for the geometric method needs a couple pythonic function as dependencies. The main ones used are:
Once these dependencies are installed, you can simply run the cb_generation.py file. All files will be saved under your path chosen. python3.9 was used for this code.
python cb_generation.py
The command line will prompt you for the file names.
The code hausdorff_dist is available for you to use, to calculate the hausdorff distance between two meshes or pointclouds.
And example output for the hausdorff distance code evaluation is:
{'RMS': 0.05054453760385513, 'diag_mesh_0': 11.399076461791992, 'diag_mesh_1': 11.315515084423572, 'max': 0.1677803099155426, 'mean': 0.039864495396614075, 'min': 6.468382451885191e-08, 'n_samples': 7619}
