Abstract
Embedded Media Markers (EMM) are optical-filter-like overlaid marks that can be printed on a part of a paper document that signify the existence of media associated with that part of the document. Users take a picture of an EMM-signified document patch using a cell phone camera, and the media associated with the EMM-signified document location is retrieved and displayed on the phone. Unlike bar codes, EMMs are nearly transparent and thus do not interfere with the document contents. Retrieval of media associated with an EMM is based on image local features of the captured EMM-signified document patch. A semi-automatically technique places an EMM at a location in a document, in such a way that the EMM encompasses sufficient identification features with minimal disturbance to the original document.
