Here my ideas:
The geometric reconstruction of object models is carried out in a way to propagate errors from inner to outer bounds.
outer bounds are enforced with orientation and placement regularities.
When I join them, if I write it as
The geometric reconstruction of object models is carried out in a way to propagate errors from inner to outer bounds which are enforced with orientation and placement regularities.
I hope this is correct.
My question is, can I omit "which are" and continue like, "... bounds enforced..."?
