Multimedia search and retrieval using multimodal annotation propagation and indexing techniques

In this paper, a complete solution for search and retrieval of rich multimedia content over modern databases is presented. The framework proposed in this paper combines the advantages of multimodal search with those of annotation propagation into a unified system. Moreover, an effective technique, which is appropriate for large-scale indexing, is adopted, extended and integrated to the proposed framework so as to achieve optimized search and retrieval of rich media content even from large-scale databases. ► We provide a new multimodal descriptor for rich media representation. ► We achieve multimodal annotation propagation with minimum manual annotation. ► Annotation propagation is exploited for multimodal search to improve accuracy.
