Just matchmover.

You need to solve for the camera motion by tracking static features in the plate.. the cracks, etc. Then you need a seperate solution for the elephant's head motion. You
get that by tracking points on the head itself. It's going to track the head as
if its a rigid object, so the points on the head you track, you'll get back in your
3d soft as points, with a single animated 'parent' null or zero object.

You use those points as part of your 3d mesh to build the base object. In this
case, the crest of the head.
