TypeSafe.BoxAnswer (typesafe_ex v0.2.1)

The answer to a TypeSafe.Box: where something is in an image.

The edges are fractions from 0 to 1, measured from the image's top-left corner: left and right of its width, top and bottom of its height. Use pixels/3 to scale them to an image of known size.

confidence - how sure the model is, from 0 to 1, or nil when it doesn't say

There is no "not found" answer: a target that isn't there still gets a box, with low confidence. Ask a TypeSafe.noul/2 about presence in the same call and ignore the box when that comes back low.
