You can using Motion Tracker in Ae then Check the Scale option in tracker window which will scale the image according to the track.

or try to use Mocha Ae which will give you full control over tracking object with Respective, Rotation, Scale, Shear and Transform.

Go to Animation>Tack Motion

If you have a way to matte out the background you could try a camera track on the subject.

The reason this won’t normally work is because the track points in the background will contribute much more to the solve. The subject won’t fit into the solution and its tracker points will not be considered. If you remove the background from the equation then AE will attempt to solve with what it has, which is the foreground subject.

Motion is relative, so whether it’s the camera moving or the ‘world’ (world meaning your subject in this case) moving around the camera there’s the potential to get a usable track.

This still may not work. It’s much less likely to work if the parts of your subject are rotating independently. If, for example, they’re walking toward the camera, and they look to the left, then to the right the camera tracker will see different parallax on the face than the body and this may contribute to errors in the solve.

There’s a lot that could go wrong, but also the potential to be pleasantly surprised at a usable solve 🙂 Worth a try in my opinion.
