Abstract

An MMR system for processing image queries across index tables with unequal priority comprises a plurality of mobile devices, a pre-processing server or MMR gateway, and an MMR matching unit, and may include an MMR publisher. The MMR matching unit receives an image query from the pre-processing server or MMR gateway and sends it to one or more of the recognition units to identify a result including a document, the page, and the location on the page. The MMR matching unit includes a dispatcher, a plurality of recognition units, and index tables, as well as an image registration unit. In one embodiment, the system includes an MMR matching plug-in installed on the mobile device. The present invention also includes methods for processing image queries across index tables of unequal priority and updating a high priority index based on received or projected image queries.
