International Workshop OntoImage’2006 Language Resources for Content-Based Image Retrieval

in conjunction with LREC’2006

Deadline for Abstract Submissions: February 20th 2006
Submission per email to: Gregory.Grefenstette@cea.fr

Background

The “semantic gap” between low-level image description (texture, shape, color) and what people perceive in images is recognized as a difficult and unsolved problem by all content-based image researchers. With the growing number of images being created and stored each day, progress must be made on automatic methods for indexing and retrieving images based on their content. The vocabulary that would be most effective for this indexing is poorly understood today.

A number of approaches for using text to retrieve image have been proposed (hand assignment of descriptions [e.g. FLICKR, GRAPHICOBSESSION]; extracting terms from captions and from text linked to images [GOOGLE]; associating word and image characteristics [Barnard et al., 2003; Dance et al., 2004]. Recently, ontologies have been suggested as the proper representation for image indexing [Town & Sinclair, 2004]. Much work remains to be done to understand the problem from a lexical point of view.

This half-day workshop will present up to 9 papers examining problems concerning the lexical characteristics of the language that can or should be used to describe image content. The goal of the workshop is to address the following questions:

· What vocabulary should be used to describe images?

· How can vocabulary items be automatically associated with images for indexing and retrieval?

· What visual characteristics of images can be discovered by text processing (color, size, location, shape, texture)?

· What elements in a lexicon correspond to visualisable objects?

· What language resources exist and what other ones are needed for content-based image retrieval?

· Can specific ontologies be created and automatically populated for content-based image retrieval?

· Can text processing identify what objects would appear against what background (e.g. bird against a sky)?
