Abstract
The present invention relates to systems and methods for characterizing targets, e.g., trucks, pallets, trains, cars, and the like, using digital target imaging. Accordingly, embodiments of the present invention provide, at base: a) image segmentation and filtering to identify surrounding white space, interior walls, floor, and ceiling of the container; morphology routines to identify and classify objects found inside the container; and decision routines to report status of container as empty or non-empty with a confidence factor from 1-100.
