PPFT2D

Two-dimensional pseudo-polar Fourier Transform

MATLAB package to compute the 2D pseudo-polar Fourier transform and the discrete 2D Radon transform.

The functions are written in MATLAB and do not use any external packages.

All functions are documented using Matlab's comments. For help on any function in the package type help function_name

See RadonPackage.pdf for more details

Getting started

1. Add folder to the MATLAB path (you can run initpath for that).
2. Run testRadon.m
3. See RadonPackage.pdf for more details
