OpenMVG v1.4 “Chinook Salmon” is out

What's new:

• 14 PR has been handled.
• 22 issues/features enhancement has been completed.

OpenMVG core:

Matching:

• Fix SVG matches export when images have different width or height size [#1216]
• Use reference instead of a temporary in the function named MatchesPairToMat [#1188]
• Create a RegionMatcherFactory [#1056]

Multiview:

• Fix the CVPR 2017 resection solver [#1253]
• Add an orthographic essential matrix solver "Two-View Orthographic Epipolar Geometry: Minimal and Optimal Solvers", Magnus Oskarsson, Journal of Mathematical Imaging and Vision, 2017. [#1246]

Robust-Estimation:

• Add a GMS Filter (Grid-based Motion Statistics filter) "GMS: Grid-based Motion Statistics for Fast, Ultra-robust Feature Correspondence, JiaWang Bian and al., CVPR2017 [#1049]

SfM:

• Implement a new Incremental SfM pipeline, SequentialSfMReconstructionEngine2: [#1241]

• The reconstruction initialization is done thanks to an abstract interface, SfMSceneInitializer. The reconstruction can now start from 2 to n images (n-uplets or existing poses).

• The triangulation stage considers the entire scene tracks.
• The resection stage is based on 2d-3D matching confidence.
• The reconstruction can start with existing camera poses.

• This new engine is easier to read and to customize (compact and use more abstraction).

• Sfm Data Colorization refactoring [#1252] [#1256]

• Fix a bug in ESfM_Data enum (behavior was a minor impact on control_point usage) [#1306]

software/localization:

• Extend the localization software to support any camera type in the command line [#1210]

software/SfM:

• Add openMVG_main_SfMInit_ImageListingFromKnownPoses to init OpenMVG sfm_data scene (views, intrinsics & poses) from GT dataset [#1195]:
• DTUMVS, ETH3D, Kitty, Middlebury, Strecha
• Remove useless code in IncrementalSfM [#1254]
• Add functions to export tracking data to sfm_data landmarks. enhancement [#1292]
• Move export2X and exportX binaries to software/SfM/export directory enhancement [#1268]
• Move the matcher out of a loop for to be more efficient in main_ListMatchingPairs.cpp [#1172]

Build enhancement

• User modern CMake recommendations [#1176] [#1146] [#1235] [#1147] [#1221] [#1269]
• Fix shared libraries build [#1339] [#1293] [#1286] [#1358]
• Enhance build documentation to support external libs build by Microsoft/VCPKG [#1327]
• Support Ceres-Solver 2.0 API changes [#1323]
• Enhance support of external JPEG, PNG, and TIFF libraries [#1266]

Samples

• Rewrite main_pano_converter.cpp to use the Spherical camera model enhancement [#1314]

Continuous Integration

• Enhance Travis XCode build [#1170]

Documentation

• Improve build and geodesy documentation [#1337] [#1346] [#1251]

UI

• Fix some minor issues [#1224]
