"Systems and methods for efficient vehicle extent estimation" was invented by Giancarlo Baldan (Boston).

According to the abstract* released by the U.S. Patent & Trademark Office: "Provided are methods for efficient vehicle extent estimation, which can include bounding box generation. Some methods described include determining bounding boxes surrounding detected point clusters according to tangents to convex hulls of the point clusters, and minimizing continuous functions of distances between points and bounding box sides.
