MAPTK v0.4.1 Release Notes

This release provides patches to the MAPTK v0.4.0 release to address issues.
MAPTK v0.4.1 is primarily a bug fix release with very minimal new functionality.

Updates since v0.4.0

Documentation

• Renamed README to README.md to allow GitHub to pick up on markdown formatting
• Added acknowledgements section to README.md thanking AFRL for their support
• Added a more detailed project description to README.md
• Added a class index to the Doxygen output
• Added more detail to inline Doxygen documentation, fixed some
  control words

Build System

• Updated the dashboard_git_url in the dashboard scripts to point to the
  new public Git URL on GitHub
• Updated CTEST_DROP_SITE to support both a public dashboard and a private
  dashboard at Kitware for testing unreleased changes

Core Library

• Added a log message for an error condition in track_features_default.cxx
  where dependent algorithms were not all initialized
• Added "virtual" keyword to algo type_name() and impl_name() methods in
  derived classes. The keyword is not required here, but makes it more
  apparent that these are virtual methods.
• Made destructor for compute_ref_homography_default class virtual

Fixes since v0.4.0

Build System

• Added missing include directory path in CMake for PROJ
• Fixed the find module procedure for PROJ to work with
  newer versions of CMake
• Fixed the issue with building statically on Windows by applying
  __declspec(dllimport) only in the shared build case
• Fixed CMake config file configuration. Added missing build directory
  reference in build config, and fixed pathing in install config

Core Library

• Call loop closure on the first frame in the default tracker to fix
  off-by-one bug in the loop closure reference frame and resulting
  homography file

OpenCV Library

• Fixed crash caused by a NULL info structure returned by
  cv::Algorithm::info(). Must check that the info object is not NULL
  before calling its name() method.
• Fixed compatibility with OpenCV when compiled without the nonfree module.
  If nonfree is available, SURF is used by default. If nonfree is not
  available, ORB is used by default.
