Eucalc is a C++\ Python library that implements algorithms to efficiently compute topological integral transforms (Euler characteristic transforms, Radon transforms and hybrid transforms) on cubical complexes. It can be used as a header library for C++ users, or can be compiled into a Python module.
This repository is associated with our paper with S. Oudot accepted in Symposium on Experimental Algorithms (SEA) 2024.
Please find short usage tutorials in the notebooks of the tutos directory.
To use our C++ code in Python we use Cython. To compile the module, we included the necessary headers from the GUDHI library in src/gudhi.
To compile Eucalc, open the main directory into a terminal and execute:
python3 setup.py build_ext --inplace
Then copy-paste the file eucalc.XXX.so to the directory you are working in or start your Python file or Jupyter notebook with:
import sys
sys.path.append('eucalc_directory')
import eucalc
where eucalc_directory is the main directory of this repository. You can start using Eucalc!
