Implementation of Radon algorithm in C++ with Qt interface

How to run on macOS:

1. Install opencv and qt

brew install qt5 opencv3
echo 'export PATH="/usr/local/opt/opencv@3/bin:$PATH"' >> ~/.bash_profile
export LDFLAGS="-L/usr/local/opt/opencv@3/lib"
export CPPFLAGS="-I/usr/local/opt/opencv@3/include"
export PKG_CONFIG_PATH="/usr/local/opt/opencv@3/lib/pkgconfig"

2. Compile the project:

qmake && make

3. Run compiled binary

radon.app/Contents/MacOS/radon

radon's Issues

fragments in Radon space around -90°

Hi,
concerning radon.cpp:
There seems to be an issue with calculation the Radon space values around -90°.
Fragments can be seen in the linked example sinogram (angles from -180° to +180°):

The reason might be dividing by zero here

radon/radon.cpp

Line 72 in 5b227d8

float alpha = - sinTheta / cosTheta;

or here

radon/radon.cpp

Line 75 in 5b227d8

float beta = (rho(r, R) - rhoOffset) / (dX * cosTheta);

Is there an easy fix to this?
Thanks

ui_mainwindow.h not found

Hi, can't find ui_mainwindow.h file which is imported in line 12 as
#include "ui_mainwindow.h"
of mainwindow.h file.

Code lacks LICENSE file
