• Bug Reports: https://github.com/karlotness/adrt/issues

This library provides an implementation of an approximate discrete Radon transform (ADRT) and related routines as a Python module operating on NumPy arrays. Implemented routines include: the forward ADRT, a back-projection operation, and several inverse transforms. The package documentation contains usage examples, and sample applications.

Installation

Install from PyPI using pip:

$ python -m pip install adrt

For further details on installation or building from source, consult the documentation.
