Indexing and matching multiple-attribute strings for efficient multimedia query processing

Multimedia data can be represented as a multiple-attribute string of feature values corresponding to multiple features of the data. Therefore, the retrieval problem can be transformed into the q-attribute string matching problem if q features are considered in a query. A general solution is proposed in this paper. It includes an index structure and the matching methodologies, which can be applied on different values of q. The experiment results show the efficiency of the proposed approach.
