Tried cross-corr for sum of keypoint 2D speeds
Tried cross-corr for sum of keypoint vertical speeds
Tried cross-corr for sum of keypoint vertical positions
Tried idem with sum of all keypoints vs selected keypoints
Tried idem with sum of weighted selected points (L190 synchronize_cams_draft deleted)
Tried idem with only right/left side
Tried idem with frames around a specified time
Tried cross-corr for each kpt, select top N highest correlations, take median offset (L244 synchronize_cams_draft deleted)
Tried cross-corr for each kpt, weighted by correlation
Tried threshold on vmax thresh
Tried correlation threshold
-> Best results (accuracy, simplicity, speed): sum of vertical speeds.
Default: all keypoints, all frames. User can also choose specific keypoints at specific instants.

Single-trial mode:

Batch mode still available
Also works with a simpler folder structure, filled with a Config.toml file, a calibration folder, and a pose folder

What's Changed

Process non filtered data if there is no data filtered in folder by @ANaaim in #86
objp should not be objp_not_used by @ANaaim in #91
Synchronization & single-trial mode by @davidpagnon in #94

v0.7.2

b21846a

Much faster and more robust multi-person analysis

Calculation of the distance between epipolar lines (simple dot product, so quite fast) -> affinity matrix -> association across views (inspired by the easymocap approach)
Association across frames is done in triangulation.

Used to be based on a very computationally ineffective combinatory approach.

For a very challenging scene: 1h30 minutes -> 2 minutes.
As fast as easymocap, and more robust on my test scenes.

What's Changed

Change of the testing of Calib and calib to work properly by @ANaaim in #78
Synchronize multi cams based on keypoints speed. by @hunminkim98 in #76
Faster and more robust multi-person analysis by @davidpagnon in #85

Multi-person analysis

Sort people across view, and then across frames.

Set [project] multi_person = true for each trial that contains multiple persons.
Set [triangulation] reorder_trc = true if you need to run OpenSim and match the generated .trc files with the static trials.
Make sure that the order of [markerAugmentation] participant_height and participant_mass matches the order of the static trials.
