The following is still from the first page of the paper:

II. ACTIVE APPEARANCE MODELS
Dynamic Appearance Models (AAMs) [1, 2] are generative
parametric models intended to
catch varieties in shape and
appearance for a particular class of items. AAMs are built
utilizing a bunch of
pictures where
the spatial places of
important milestones, xi = (xi, yi)T ∈ R2, are characterized
to address the items shape.
These tourist spots are explained
physically ahead of time.

Clearly, the AI has substituted "dynamic" for "active", and it also seems that "catch" is substituted for "detect", "varieties" for "changes", and "pictures" for "images".
The phrase "the spatial places of important milestones" might be something like "locations of waypoints(?)", but it is hard to know.
That phrase "the spatial places of important milestones" seems to correlate with the phrase "these tourist spots" in the final quoted sentence above. I am guessing "are explained physically ahead of time" might make the last sentence a twisted version of "These locations/waypoints are predetermined.".
But I (oh so sarcastically) say, "What unnamed person has cognizable epistemic epiphanies along this ground-based trajectory?"
