    • Multimedia information retrieval is performed using meta-descriptors in addition to descriptors. A “descriptor” is a representation of a feature, a “feature” being a distinctive characteristic of multimedia information, while a “meta-descriptor” is information about the descriptor. Meta-descriptors are generated for multimedia information in a repository (10, 12, 14, 16, 18, 20, 22, 24) by extracting the descriptors from the multimedia information (111), clustering the multimedia information based on the descriptors (112), assigning meta-descriptors to each cluster (113), and attaching the meta-descriptors to the multimedia information in the repository (114). The multimedia repository is queried by formulating a query using query-by-example (131), acquiring the descriptor/s and meta-descriptor/s for a repository multimedia item (132), generating a query descriptor/s if none of the same type has been previously generated (133, 134), comparing the descriptors of the repository multimedia item and the query multimedia item (135), and ranking and displaying the results (136, 137).
    • 除了描述符之外,使用元描述符执行多媒体信息检索。 “描述符”是特征的表示,“特征”是多媒体信息的独特特征,而“元描述符”是关于描述符的信息。 通过从多媒体信息(111)提取描述符,通过基于描述符(112)对多媒体信息进行聚类,为存储库(10,12,14,16,18,20,22,24)中的多媒体信息生成元描述符 ),向每个集群(113)分配元描述符,以及将所述元描述符附加到所述存储库(114)中的多媒体信息。 通过使用逐个示例(131)制定查询,获取存储库多媒体项目(132)的描述符和元描述符/ s来查询多媒体存储库,生成查询描述符/ s,如果没有相同的 先前已经生成了类型(133,134),比较存储库多媒体项目和查询多媒体项目(135)的描述符,并对结果进行排序和显示(136,137)。
