Abstract
A MMR system for publishing comprises a plurality of mobile devices, an MMR gateway, an MMR matching unit and an MMR publisher. The mobile devices send retrieval requests including image queries and other contextual information. The MMR gateway processes the retrieval request from the mobile devices and then generates an image query that is passed on to the MMR matching unit. The MMR matching unit receives an image query from the 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 an image registration unit that receives new content from the MMR publisher and updates the index table of the MMR matching unit. A method for automatically registering images and other data with the MMR matching unit, a method for dynamic load balancing and a method for image-feature-based queue ordering are also included.
