This failure detection - was well-intended, trying to prevent poor solutions from getting - made without notifying the caller. Unfortunately in practice, this - threshold is too conservative. Furthermore, it is not clear the - threshold should exist at all; the purpose of the Euclidean - resection is to come up with the best solution it can; other - methods (e.g. reprojection error) should be used to compare - whether the method succeeded. - - This commit changes the Euclidean EPnP code to always succeed, - causing the previous fallback to projective resection to never - run. In most cases, this will result in better reconstructions. - - This should, in most cases, fix the dreaded "flipping" problem. - -commit 57dad861d2a7f9d058c6d8edde1a2d51d7225a51 -Author: Keir Mierle <mierle@gmail.com> -Date: Thu Sep 20 02:27:34 2012 +0000 - - Fix variable naming in the planar tracker. - -commit e9392fd3b46f5668662935696e7d9afac3390ca4 -Author: Keir Mierle <mierle@gmail.com> -Date: Thu Sep 20 02:10:33 2012 +0000 - - Add smarter tolerance checking in the planar tracker. - - The planar tracker uses Ceres for the refinement stage. During - refinement, Ceres iteratively updates the parameters with the - latest best guess. If the change in the parameters falls below a - threshold, Ceres will abort successfully ("converged"). - - For the case of pure translation tracking, the parameters are - exactly the two pixel shifts (dx, dy), and measuring the change in - these parameters gives a meaningful termination criterion. - However, for all the other parameterizations like affine, where - the parameterization involves affine parameters that have no - physical interpretation, Ceres is left with no way to terminate - the solver early. With the existing code, often many iterations - are run long after Ceres has found a solution sufficiently - accurate for all tracking needs. No one needs tracking with - a quadrillionth of a pixel accuracy; that time is wasted. - - This patch extends the existing iteration callback that is passed - in to Ceres to check if the pattern has fallen out of the search - window, to also check if the optimizer has made a tiny step. In - particular, if the maximum shift of any patch corner between two - successful optimizer steps is less than a threshold (currently - 0.005 pixels), the track is declared successful and tracking - is terminated. - - This leads to dramatic speed increases in some cases, with little - to no loss in track quality. This is especially apparent when - tracking patches with affine or perspective motion models. For - example, on some tracking cases I tried, the iterations Ceres took - went from 50 to 3. - -commit 36729c19bf90cb767e9adb96ba7dd48a5ace2be1 -Author: Keir Mierle <mierle@gmail.com> -Date: Wed Sep 19 22:25:02 2012 +0000 - - Detect too-small planar tracking patches. - - The planar tracker did not detect very skinny patches which have - effectively zero area and are untrackable. This adds detection and - rejection of patterns with zero area. This fixes a crash found by - during Mango production. - -commit 5cf2bae255a5a0f2e36ea0516670782cb88b589d -Author: Sergey Sharybin <sergey.vfx@gmail.com> -Date: Thu Dec 6 17:33:53 2012 +0600 - - Real fix for previous commit from Keir. He's comment; - - Cleanup for when trackers fall out of the search window. - - Sergey originally left a TODO() here, but his fix is the correct - one. I removed the TODO and fixed some comment issues. - -commit a11533918720e5b43dc1e95895db0eb36c8c06aa -Author: Sergey Sharybin <sergey.vfx@gmail.com> -Date: Thu Dec 6 17:31:16 2012 +0600 - - Fix crash when tracking in planar motion model (and maybe some other) - - It was an Abort() caused by check for solver result not equal to USER_ABORT. - - In some cases solver returns USER_ABORT due to BoundaryCheckingCallback - detects coordinates does not belong to image. - - Somehow this callback wasn't called in previous version of Ceres and - in the same case marker was jumping. Now when the callback is called - it seems we could simply return failure of tracking without aborting - Blender. - - Probably this is in fact some issue somewhere else, would double - check with Keir about this. - -commit 4be2306bcc664b259aaf7068b9f32ab60124a509 -Author: Sergey Sharybin <sergey.vfx@gmail.com> -Date: Thu Dec 6 17:29:39 2012 +0600 - - Resolved some compilation warnings (missed prototypes) - - In some cases it was missed include of header file, in some other - cases symbol could be static. - -commit bef729ba5c12683d13584d2a728b8b6506b7ca90 -Author: Sergey Sharybin <sergey.vfx@gmail.com> -Date: Thu Dec 6 17:27:17 2012 +0600 - - Code cleanup: silence some -Wnarrowing warnings from C++11 - -commit add1415d896818367087c784a3013dd8f1bb2095 -Author: Sergey Sharybin <sergey.vfx@gmail.com> -Date: Thu Dec 6 17:25:18 2012 +0600 - - Changes to SamplePlanarPatch to support mask input and - added output for pattern center. - -commit daa354c0735b954b0cd7725626e9a3d67416d46b -Author: Keir Mierle <mierle@gmail.com> -Date: Sat Jun 9 19:22:39 2012 +0000 - - Change libmv's bilinear sampling to assume the same - pixel conventions as Blender.

This should - reduce the "jumpiness" that is sometimes seen when doing - non-"Loc" tracks. - - It is disabled in this commit; a subsequent commit will add - controls to the tracking dialog for this. - -commit a1c5a70badd11cba0470700bad2eac2b2bd30c86 -Author: Keir Mierle <mierle@gmail.com> -Date: Sat Jun 9 06:55:21 2012 +0000 - - Planar tracker polish. - - - Fixes the correlation checking code that was broken in the - previous commit. The bug was a transpose error. - - Fixes a memory leak of the warp functor, found by Sameer. - - Various cleanups done at Sameer's suggestion. - - Thanks to Sameer Agarwal for a code review. - -commit 2cb784caa854a77cdd43620ab133f26b87ed0d83 -Author: Keir Mierle <mierle@gmail.com> -Date: Fri Jun 8 17:42:17 2012 +0000 - - Make planar tracking much faster. - - - This makes planar tracking around 2-3x or more faster than - before, by rearranging how the sampling is done. - Previously, the source patch was sampled repeatedly on - every optimizer iteration; this was done for - implementation speed, but was wasteful in computation. - - - This also contains some additions to Ceres to help - deailing with mixed numeric / automatic differentation. In - particular, there is now a "Chain::Rule" operator that - facilitates calling a function that takes Jet arguments, - yet does numeric derivatives internally. This is used to - mix the numeric differentation of the images with the warp - parameters, passed as jets by Ceres to the warp functor. - - There is also a new "JetOps" object for doing operations - on types which may or may not be jets, such as scaling - the derivative part only, or extracting the scalar part - of a jet. - - This patche is aimed at Ceres upstream. - - - A new function for sampling a patch is now part of the - track_region.h API; this will get used to make the preview - widget properly show what is getting tracked. Currently - the preview widget does not handle perspective tracks. - - Known issues: - - This patch introduces a bug such that the "Minimum - Correlation" flag does not work; if it is enabled, tracking - aborts immediately. The workaround for now is to disable the - correlation checking, and examine your tracks carefully. A - fix will get added shortly. |
