In this paper,firstly we introduce the context of MPEG-7,MPEG-7 objectives and parts. Then we analyze the MPEG-7 eXperimentation Model(XM) reference software, including application types,software models and the implementation of descriptors and description schemes. Finally we discuss the possible application of MPEG-7 in AVTMS.展开更多
