Goal:creation of a large-scale image ontology • WordNet lexical resourses • Image collections acquisition through web-based image mining
WordNet lexical resources basis of ontology list of portrayable objects Building a large-scale image ontology for object recognition:
visual features semantic filtering clustering classification web-based image mining large-scale visual dictionary Building a large-scale image ontology for object recognition:
ENTITY has a distinct separate existence (living or nonliving) OBJECT physical object (a tangible a visible entity) object living thing life wildlife object living thing plant … tree tree of knowledge object artifact creation classic deleted Pruning approach to WordNet simplifying connections selecting branches
ENTITY 102 nodes in total object living thing natural object artifact floater organism celestial body article commodity rock consumer goods Extraction from top-level ontology of portrayable objects
web-image search engine (Alltheweb) indexing (PIRIA – LIC2M) clustering (shared nearest neighbor) visualisation of clusters VIKA (Visual Kataloguer)
queries to the web (e.g. google image) List of portrayable objects (24000 items) VIKA (Visual Kataloguer)
word identifying portrayable object + upper node Example of queries: Japanese pagoda • kino tree • red sandalwood tree • carib wood tree • Japanese pagoda tree • palm tree • ... buildings Japanese pagoda tree trees Composition of queries:
query « chair» Web-image search at present Desired results
Future work: • face detection (adaboost learning) – to filter web-image search results semantically (images of objects without people) • testing VIKA system performances • automatic cluster classification – ignoring irrelevant clusters • introducing new connections to the ontology: vision principles (scale), co-occurrence rules
Future work Vision principles (scale)
Future work Co-occurrence rules
