Outlined below are examples of military target characterization and tracking derived from a variety of imagery data sources, from multiple points of view, and in different lighting conditions.
The U.S. military continues to pursue technology that will radically improve capabilities to find, identify, and track targets anywhere on the globe, in all environments, wherever imagery can be obtained.
Structures, Vehicles, People
Bézier curves do more than place a rectangular box around people, vehicles, and weapons, they find, characterize, and make decisions based upon their actual shape.

The process of extracting topographic features such as ridge lines, peaks, skylines, and river banks taken at or near-ground levels is time consuming, tedious, and frequently requires adjustment for occlusions and varying meteorological conditions. Bézier curves can be used to quickly and efficiently create terrain signatures for navigation, forensic search, and mapping.
