An MMR system integrating image tracking and recognition 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. Image tracking information also is provided for determining relative locations of images within a document page. The mobile device includes an image tracker for providing at least a portion of the image tracking information. The present invention also includes methods for image tracking-assisted recognition, recognition of multiple images using a single image query, and improved image tracking using MMR recognition.
