Abstract
A license plate recognition process is described that includes automated image analysis integrated with human review and a definition of a plate grammar of license plate visual elements that are required to prepare a database search index that enables selection of a particular license plate, from a known population of all possible license plates issued for each and every jurisdiction of interest. The plate grammar includes visual elements that may be searched by both automated image analysis and by a human reviewer. The process includes creation of a question that guides a human reviewer into providing required information regarding a selected plate grammar element that is not identified by computerized image analysis. Integration of a manual review process within an automated process as opposed to manual review solely at a failed completion of the automated process is included. Methods are presented for creation of queries for manual review that take into account the skill and availability of the manual reviewer as well as optimizing for a shortest path to completion of the recognition of the license plate through the database search index.
