+
+    Update Ceres to the latest upstream
+    
+    This brings up much easier termination type usage,
+    which for us means we might use:
+    
+      ceres::Summary::IsSolutionUsable()
+    
+    instead of doing manual funky enum values check.

+
+    Eagerly attempt to refine a track before doing a brute search
+    
+    Before the refinement phase of tracking, a brute force SAD search
+    is run across the search area. This works well but is slow;
+    especially if the guess for the track's location is accurate.
+    
+    This patch runs a refinement phase before running a brute force
+    search, hoping that the guessed position (in x2, y2) is close to
+    the best answer. If it is, then no brute search is done. If it is
+    not, then a normal brute force search followed by refinement is
+    done.
+    
+    In some cases this may produce worse tracks than before; the
+    regressions will need investigation. The predictive motion model
+    (to be implemented) will reduce the probability of that happening.

+
+    Fix bug where libmv tracking incorrectly succeeds on failure
+    
+    Before this patch, if Ceres returned USER_SUCCESS indicating that
+    Ceres was only changing the tracked quad slightly between
+    iterations (indicating convergence), no final correlation check
+    was done. This leads to incorrectly returning that the tracking
+    was successful, when it actually failed.

+
+    Implementation of weighted tracks
+    
+    Added a weight field to Track structure which means
+    how much affect this track will have on the final
+    reconstruction.
+    
+    Currently it affects on BA step only which in most
+    cases will work just fine. However, it worth looking
+    into weight support for intersection/resection.

+    Get rid of Allow Fallback option for euclidean resection
+    
+    It was rather confusing from the user usage point of view
+    and didn't get so much improvement after new bundle adjuster
+    was added.
+    
+    In the future we might want to switch resection to PPnP algorithm,
+    which could also might be a nice alternative to fallback option.

+
+    Implement refinement of estimated homography/fundamental matrices
+    
+    It was only possible to perform algebraic estimation, which didn't
+    give so much accurate results.
+    
+    Implemented a way to perform algebraic estimation followed with
+    refinement step using Ceres minimizer.
+    
+    The code was actually mostly already there since keyframe selection
+    patch. Made such estimation a generic function in multiview/ and
+    hanged API for estimation in order to pass all additional options via
+    an options structure (the same way as it's done fr Ceres).
+    
+    Most of the options are straight-forward to understand,but some
+    deserves more description here:
+    
+    * expected_average_symmetric_distance is used as an early output check
+      and as soon as average symmetric error goes below this threshold
+      refining finishes.
+    
+      This distance is measured in the same units as input points are.
+    
+      It is arguable whether we need callback for this or not, but seems
+      Ceres doesn't have some kind of absolute threshold for function value
+      and function_tolerance behaves different from logic behind expected
+      symmetric error.
+    
+    * There' an option to normalize correspondences before estimating the
+      homography in order to increase estimation stability. See
+    
+        R. Hartley and A. Zisserman. Multiple View Geometry in Computer
+        Vision. Cambridge University Press, second edition, 2003.

+
+    Add Procrustes PNP ("PPnP") resection algorithm to libmv
+    
+    This adds a new Euclidean resection method, used to create the
+    initial reconstruction in the motion tracker, to libmv. The method
+    is based on the Procrustes PNP algorithm (aka "PPnP"). Currently
+    the algorithm is not connected with the motion tracker, but it
+    will be eventually since it supports initialization.
+    
+    Having an initial guess when doing resection is important for
+    ambiguous cases where potentially the user could offer extra
+    guidance to the solver, in the form of "this point is in front of
+    that point".
+    
+    Original patch by Keir Mierle made to Blender repository.

-    
-    - Added includes of own header to fast implementation files.
-    
-    - Camera intrinsics wouldn't complain about unknown pragma when
-      building without OpenMP support.
-    
-    TODO: Make it a CMake option to build libmv with OpenMP support.
-    	  Currently multi-threaded intrinsics only available when

-    Multithreaded camera intrinsics
-    
-    Implemented multithreaded buffer (un)distortion
-    for camera intrinsics using OpenMP.
-    
-    By default, (un)distortion is single-threaded,
-    but it is possible to as CameraIntrinsics to
-    use more threads by calling SetThreads method.

-    
-    - Removed ceres_ prefix from ceres unit tests, only use this

-    
-    - Added unit tests data for ceres, otherwise system_test fails.
-
