adrt 1.1.0

Approximate Discrete Radon Transform

Fast approximate discrete Radon transform for
NumPy arrays.

Documentation: https://adrt.readthedocs.io/en/latest/
Source Code: https://github.com/karlotness/adrt
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

or from conda-forge:
$ conda install -c conda-forge adrt

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