嵌入式媒体标记，或简称EMM，是印刷在纸质文档上的近乎透明的图标标记，表示与文档的该部分相关的媒体的存在。EMM还指导用户的相机操作以进行媒体检索。用户使用手机拍摄EMM标志的文档补丁的图片，并且与EMM标志的文档位置相关联的媒体显示在手机上。与条形码不同，EMM几乎是透明的，因此不会干扰文档外观。与EMM相关联的媒体的检索基于所捕获的EMM标志的文档补丁的图像局部特征。本文介绍了一种技术，用于半自动地将EMM放置在文档中的一个位置，以这样一种方式，它包含了足够的识别功能，对原始文档的干扰最小。
Embedded Media Markers, or simply EMMs, are nearly transparent iconic marks printed on paper documents that signify the existence of media associated with that part of the document. EMMs also guide users' camera operations for media retrieval. Users take a picture of an EMM-signified document patch using a cell phone, and the media associated with the EMM-signified document location is displayed on the phone. Unlike bar codes, EMMs are nearly transparent and thus do not interfere with the document appearance. Retrieval of media associated with an EMM is based on image local features of the captured EMM-signified document patch. This paper describes a technique for semi-automatically placing an EMM at a location in a document, in such a way that it encompasses sufficient identification features with minimal disturbance to the original document.
