- Deduplicate patetrn sampling used in esm and lmicklt trackers and
move SamplePattern to image/sample.h - Move computation of Pearson
product-moment correlation into own function in new file image/correlation.h
so all trackers can use it to check final correlation.
- Remove SAD tracker. It's almost the same as brute tracker, with only two differences:
1. It does brute search of affine transformation which in some cases helps to track
rotating features 2. It didn't use common tracker api which probably gave some
speed advantage, but lead to a real headache to use it together with other
trackers leading to duplicated code in blender side.
- Switch blenedr to use brute tracker instead of sad tracker which tracking made
source code much more simple to follow.
(median point was sliding a bit from it's original position)
This happens because of how transformation for stabilization calculates:
image is scaling around it's center, so image translation should be recalculated
after scale was changed, but scale also depends on translation. That's where
tricky things happens. It's still not ideal for case of rotation, but before
fixing this issue better to figure out usecase and see if it's indeed
so needed to scale around image center (it might only be helpful to use
stabilization parameters in compositor nodes).
- Ron aspect ratio correction after applying location
There're still some annoynments with rotation stabilization with
pixel aspect != 1, will be fixed later.
- Joining tracks will update track used for rotation stabilization/
- If track was hidded in clip editor it wasn't highlighted in 3d viewport
even if it's selected.
- If two tracks has got the same bundle coordinate and one of them is
selected it might not be highlighted in 3d viewport because of
draw order.
- Fixed tooltip displaying for track sequence forwards in clip editor
- Corrected detection of 8 tracks so it wouldn't count tracks disabled
on keyframes.
- Scale track preview to actual track widget size instead of scaling the
whole preview image with given zoom ratio, so no extra memory needed to
store zoomed margin would be used.
- Track's statistics text will fit pattern position instead of search if
marker is disabled on current frame.
- Fixed toggle selection operator if selected track is hidden due to
"Hide Disabled" policy.
This commit extends limit of ID and objects to 64 (it means 63 meaning
characters and 1 for zero-terminator). CustomData layers names are also
extended.
Changed DNA structures and all places where length constants were hardcoded.
All names which are "generating" from ID block should be limited by MAX_ID_NAME-2,
all non-id names now has got own define called MAX_NAME which should be used all
over for non-id names to make further name migration stuff easier.
All name fields in DNA now have comment with constant which corresponds to
hardcoded numeric value which should make it easier to further update this
limits or even switch to non-hardcoded values in DNA.
Special thanks to Campbell who helped figuring out some issues and helped a lot
in finding all cases where hardcoded valued were still used in code.
Both of forwards and backwards compatibility is stored with blender versions newer
than January 5, 2011. Older versions had issue with placing null-terminator to
DNA strings on file load which will lead to some unpredictable behavior or even
crashes.
This commit implements basic clipboard support for movie tracking data
int clip editor. Used own implementation of clipboard like it's done
for sequencer.
Ideally it needed to be switched to more general clipboard system, but
currently this system is designed for text data only and it need to
be re-designed itself. But this feature is quite useful since object
tracking is implemented, so it should be OK to live with such own
implementation for a while.
- marker_find_frame moved to MovieTrack.markers and called find_frame
- Added MovieTrack.markers.insert_frame to insert marker at specified frame
- Added MovieTrack.markers.delete_frame to delete marker from specified frame
This commits merges object tracking implementation from tomato branch.
Summarized changes from branch:
- Added list of objects to be tracked. Default there's only one object called
"Camera" which is used for solving camera motion. Other objects can be added
and each of them will have it;s own list of tracks. Only one object can be used
for camera solving at this moment.
- Added new constraint called "Object Tracking" which makes oriented object be
moving in the save way as solved object motion.
- Scene orientation tools can be used for orienting object to bundles.
- Object has got scale to define "depth" in camera space.
- All tools which works with list of tracks or reconstruction data now
gets that lists from active editing object.
- All objects and their tracking data are available via python api.
- Improvements in witness cameras workflow,
- Enable bicybic filtering fir image displayed in track preview
- Option to show grayscale content of track preview
- When some channels are disabled, display exactly the same
content of preview image which is sending to tracker library.

Use proper timecode flags sending to BKE_movieclip_get_ibuf_flag function,
so now frames for tracking would be full-resolution but calculated using
timecode defined in th interface,
