Fine-Tuning the Trackers
Supervised tracking can always produce the most accurate results by definition, because a human can always look at an auto-track and find something to improve. The accuracy of supervised tracking is also aided by the high accuracy offered by the pattern-matching supervised tracking algorithms.
You can tell SynthEyes to make a second pass through the images, re-tracking them using the pattern-matching supervised tracker. This fine-tuning process can give you closer to the accuracy of a careful supervised track, though it will take the computer a bit longer to process.
Trick : if you set the Key Spacing parameter to 1, ie a key on every frame, SynthEyes will leave the trackers as spot trackers and re-set all the position keys as if it was a supervised spot tracker, ie at the higher (interpolated) image resolution controlled by the Track menu.
The fine-tuning workflow adds a step as follows:
1. Run Auto-tracker on the Summary panel
2. Click the Fine-tune trackers item on the Track menu.
3. Check the parameters on the fine-tune panel, then hit Run .
4. Go to the Solver panel and click Go! to solve the shot.
You can turn on the Fine-tune during auto-track checkbox on the Fine-tune trackers dialog or summary panel to have fine tuning done during auto-tracking. Or, you can do an automatic track and solve, then decide to fine-tune and refine the solve later: the work-flow is up to you.
