| Outline of Final Research Achievements |
Aiming at maximizing user satisfaction, we have proposed a recursive ranking method for feeding back a high information relevant to a user's request to develop new generation image search engines. The validity of the proposed method has been confirmed through a number of experiments using a real image set. Search results are not fixed. It is devised to be able constantly to follow the change of user request, and we developed the controllable similarity measure by parameters. Thus, it is possible to control the degree of similarity and the order of presentation of the images, such functionality has not been intended in the conventional search engines. The results can be deployed in many applications.
