This replaces the old style tracker configuration panel with the new planar tracking panel. From a users perspective, this means: - The old "tracking algorithm" picker is gone. There is only 1 algorithm now. We may revisit this later, but I would much prefer to have only 1 algorithm. So far no optimization work has been done so the speed is not there yet. - There is now a dropdown to select the motion model. Choices: * Translation * Translation, rotation * Translation, scale * Translation, rotation, scale * Affine (Not implemented yet) * Perspective The most stable is the "translation" parameterization. The others work but still require some tweaking. - The old "Hybrid" mode is gone; instead there is a toggle to enable or disable translation-only tracker initialization. This is the equivalent of the hyrbid mode before, but rewritten to work with the new planar tracking modes. - The pyramid levels setting is gone. At a future date, the planar tracker will decide to use pyramids or not automatically. The pyramid setting was ultimately a mistake; with the brute force initialization it is unnecessary.
