ARS - Angular Radon Spectrum

Copyright (C) 2017-2020 Dario Lodi Rizzini.

OVERVIEW

Library ars implements the Angular Radon Spectrum method for estimation of rotation. It has been kept to a minimal design.

If you use this library, please cite the following paper:

D. Lodi Rizzini. Angular Radon Spectrum for Rotation Estimation. Pattern Recognition, Volume 84, Dec. 2018, Pages 182-196, DOI 10.1016/j.patcog.2018.07.017.

DEPENDENCIES

The software depends on the following external libraries

  • Boost (submodule lexical_cast)
  • Eigen 3.0

Other dependencies are placed in directory thirdparty. Some examples require the external application "gnuplot" to display results.

HOW TO COMPILE

Let ${ars_ROOT} be the install directory of your local copy of library ars. The following standard commands are required to compile it:

  • cd ${ars_ROOT}
  • mkdir build
  • cd build
  • cmake ..
  • make

You can also install the library into a system directory. To change the install directory you must set cmake environment variable ${CMAKE_INSTALL_PREFIX} (e.g. using command "ccmake .." before calling "cmake .."). Its default value on UNIX-like/Linux systems is "/usr/local". After compiling library ars, run the command:

  • sudo make install

The command "sudo" is required only if ${CMAKE_INSTALL_PREFIX} is a system diretory managed by administrator user root. Such command copies:

  • header files of ${ars_ROOT}/include/ars to ${CMAKE_INSTALL_PREFIX}/include/ars/
  • library files ${ars_ROOT}/lib/libars.a to ${CMAKE_INSTALL_PREFIX}/lib/
  • cmake script ${ars_ROOT}/cmake_modules/arsConfig.cmake to ${CMAKE_INSTALL_PREFIX}/share/ars/

HOW TO USE LIBRARY ars IN YOUR PROJECT

If library ars has been installed in system directory "/usr/local", then it is straighforward to use it in your projects. You need to add the following lines to your project as in this example:

CMAKE_MINIMUM_REQUIRED(VERSION 2.8)
PROJECT(foobar)

find_package(ars REQUIRED)
message(STATUS "ars_FOUND ${ars_FOUND}")
message(STATUS "ars_INCLUDE_DIRS ${ars_INCLUDE_DIRS}")
message(STATUS "ars_LIBRARY_DIRS ${ars_LIBRARY_DIRS}")
message(STATUS "ars_LIBRARIES ${ars_LIBRARIES}")

if(${ars_FOUND})
include_directories(${ars_INCLUDE_DIRS})
link_directories(${ars_LIBRARY_DIRS})
endif()

add_executable(foobar foobar.cpp)
target_link_libraries(foobar ${ars_LIBRARIES})

The above example uses the variables defined in arsConfig.cmake:

  • ars_FOUND - system has ars module
  • ars_INCLUDE_DIRS - the ars include directories
  • ars_LIBRARY_DIRS - the ars library directories
  • ars_LIBRARIES - link these to use ars
