Euler characteristic of images and finite point sets.

Project description


Compute Euler Characteristic curves and surfaces of image and point data.


For the package to install correctly the prerequisites are

  • a C++ compiler. Windows users need to install a recent version of Visul Studio
  • cmake version >= 3.8
  • pybind11 version >= 2.2

It is recommended to install both cmake and pybind11 via the conda command, which can be obtained by installing either Anaconda or Miniconda.

With conda installed run the following commands in a terminal window.

$ conda install -c anaconda cmake
$ conda install -c conda-forge pybind11

This module makes use of features provided by the following Python modules

  • numpy
  • matplotlib, used in the display module of the package
  • scipy, used to obtain Delaunay triangulations of 2D and 3d finite point sets
  • scikit-learn, for nearest neighbours algorithm to obtain an estimate of the inverse of the local density in a finite set of points


The documentation for this project is available at, where usage examples are also provided for computing both Euler characteristic curves and Euler characteristic surfaces.
