Admittedly I am pretty ignorant here, but there is a plethora of "hulls" in this reference, about imaging:

coolbrowne Nov 29, 2010:
Envelope is not (convex) hull The convex hull of a given set is the smallest convex set containing the given set, that is the intersection of all convex sets (such as half-spaces)which contain the given set. The same term is also used to denote the outer surface of said hull. The convex hull need not be smooth.

An envelope of a family of differentiable manifolds is a differentiable manifold that is tangent to each member of the family (at some point). If the manifolds are one-dimensional, they are (smooth) curves; if two-dimensional, (smooth ordinary) surfaces.

envelope

That's a well-defined term in Mathematics (see reference). In Spanish it's better known as "envolvente" (in fact "envoltória" is more common in Portuguese).

hull vs. envelope

I've done some research too and found that apparently both terms are used to refer to "envolvente" (envoltorio must be the Spanish equivalent used in Spain). "envelope", however, is the term I'm familiar with, and it seems to have a broader use than "hull" (convex hull).

Besides, since the "convex hull" is also called "convex envelope", "envelope" is, in my opinion, the safest bet in this case.

Peer comments on this reference comment:
neutral coolbrowne : In fact, it's not a matter of preference. This is Mathematics and those are two distinct mathematical concepts. Please see discussion entry.

neutral Laureana Pavon : It´s most definitely not a hull. There's no ambiguity in the concept: in this case it's an envelope
