MAPTK v0.5.1 Release Notes

This release provides patches to the MAPTK v0.5.0 release to address issues.
MAPTK v0.5.1 is primarily a bug fix release with very minimal new functionality.

Updates since v0.5.0

Tests

• Enabled Travis CI integration by adding a .travis.yml file. This provides
  continuous integration testing on topic branches. Travis CI only tests
  on a single platform (currently Ubuntu 12.04), so it does not replace
  nightly CDash testing across multiple platforms. However, it does
  automatically build topic branches and pull requests that would not be
  tested by CDash. CDash only tests builds of the master and release
  branches, but does so over a wide array of platforms and build
  configurations. Thus, Travis CI and CDash are complementary testing
  tools. Travis CI can help catch some build failures before branches
  are merged.

Tools

• Added more verbose output in the feature_tracker tool when configuration
  checks fail. Adopts the same reporting technique used in the
  maptk_bundle_adjust_tracks tool.

Fixes since v0.5.0

Build System

• Fixed some CMake configuration warnings.

Documentation

• Added missing algorithms on the MAP-Tk core Doxygen main page and sorted
  existing algorithms.
• Added missing documentation on the VXL module Doxygen main page for recently
  added algorithms and containers and sorted the lists.
• Added missing algorithms on the OCV module Doxygen main page and sorted.
• Boost chrono is required by Boost timer on all platforms when linking a
  static Boost.

OCV Module

• Swapped respective returns from width/height getter methods as they were
  previously returning the incorrect values.
• Draw tracks algorithm would not write images into a directory that did not
  exist and would fail silently. Now it creates the directory first if
  missing.

VXL Module

• Fixed a camera conversion test that was failing on some platforms. Compare
  the camera parameters directly instead of computing a 3x4 projection matrix
  for each and comparing that. Computing the matrix introduces additional
  floating point precision error which should not be a part of this test.
• Loosened some tolerances on tests that were failing on some dashboard builds
  with errors just slightly over the test tolerance.

Scripts

• Fixed Blender import KRTD script to handle image aspect ratios where the
  height is larger than width. Focal length was being interpreted
  incorrectly. Also set the rendering image resolution based on the principal
  point to get proper aspect ratio in the camera view.

Tools

• Avoid a segfault in maptk_bundle_adjust_tracks by checking that there are
  tracks remaining after filtering by minimum length. Provide an informative
  message and exit cleanly if no tracks remain.
