Charles Yeager (yeagerfilm.com) shows how to remove the camera rig from 360 footage. This technique can be applied to removing any object, where the object and camera are stationary. He uses the After Effects Mask Tool, with SkyBox Studio V2. The SkyBox Composer module gives a View-based Edit comp, so content creators can easily work with 360 footage.
