Searching and browsing large scale image database using keywords and ontology

Automatic image annotation is a promising solution to enable keyword-based semantic image retrieval. In this demo, we present our image search engine I-Search implemented using a multi-level semantic image annotation algorithm. By incorporating a domain-specific ontology into the autogenerated annotations, we are able to organize large scale natural image databases into hierarchical structures for browsing and keyword-based searching without referring to external text information.
