Moving-Object Track with GeoH Secondary Tracking in SynthEyes

GeoH tracking can be combined with regular moving object tracking, especially when there’s no preexisting model, but some secondary tracking is required, or to be able to work with an unknown or zooming lens field of view. Starting with already-tracked supervised trackers, a moving object track is accomplished, then GeoH tracking added to accommodate the opening of the box. Then two additional levels of GeoH tracking are added to deform the corners of the lid to match up better, using a two-channel gradient.
