J. Yamane et M. Sakauchi, A CONSTRUCTION OF A NEW IMAGE DATABASE SYSTEM WHICH REALIZES FULLY AUTOMATED IMAGE KEYWORD EXTRACTION, IEICE transactions on information and systems, E76D(10), 1993, pp. 1216-1223
Recently, a flexible image database retrieval system where image keywo
rds can be captured automatically is strongly required, in order to ma
nage a practical number of image data successfully. However, image rec
ognition/understanding technology level is not generally sufficient en
ough to achieve this requirement. In order to overcome this problem, a
new type of image database framework is proposed in this paper. In th
e proposed system, image keywords are extracted in fully-automated fas
hion by the flexible and generalized image recognition system. Image k
eywords employed in this system are a collection of recognized objects
in the image, where achieved recognition levels are allowed to be int
ermediate or imperfect. The concept of ''recognition thesaurus'' has b
een introduced to manage these various abstraction level of keywords s
uccessfully. As an embodiment of this concept, an experimental image d
atabase with various types of sports scenes has been implemented and v
arious retrieval evaluations have been performed. Experimental results
reveal the effectiveness of the proposed method.
