Subjective aspects in image database system

These days, development of computer device leads to computer user explosion. On the other hand, conventional technology cannot handle user diversity, because computer cannot treat each user subjectivity. It is important to materialize techniques which can answer user subjective requests flexibly for coming new media epoch. This research focuses on studying how subjective impressions are grounded in physical perceptions, especially in visual perception. In this paper we propose a model for subjectivity and physical perceptions, and give an example in image database system. We introduced the image database system which can answer user subjective requests based on the visual perception model. It may be possible to apply a system which can suit each user´s characteristic and increase the user friendliness of the system even more
