An Experiment of Realization of Fully Automated Keyword Extraction in Image Database System

Recently, a flexible image database retrieval system where iniage keywords call be captured automatically is strongly ~equired, to manage a practical Iium1)er of image data sl~ccessfully. But image recognit io~i /~~nderstar i t l i~ig technology level is not generally inefficient enough to achieve this requirement. I11 order to overcome this problem, we propose a new i~iiag(, data1)ase framework here. In the proposed syst rm, image keywords ale extracted in fully-automated fashion by the deviced image recognition system. Image keywords used here is a collection of recognized objects in the image, where recognition levels are allowed to be intermediate or imperfect. We introduce the concept of "recognition thesaurus" for managing these various level keywords successfully. As an eml~otliment of this concept we implemented an image datal~ase with various types of sports scenes. Retrieval evaluations reveals the effectiveness of the proposed method.
