First we start by keeping track of the items that need replacing. For example, this one needs to be replaced by a TV. First we track the four corners of the TV.

Once tracked we can bake paths to make our objects follow the tracked path. This allows us to replace items. We can also edit the replacement items by using properties such as deformation.
