This retrieval system composes of the following five steps: abstracting features of images, abstracting image refinement and edge information, securing necessary information from analysed features, retrieving secured information from database, and comparing and abstracting images from retrieved databases. The proposed retrieval system aims at quick and exact retrieval, which is to be demonstrated through simulation. Keyword : histogram refinement, gray scale, horizontal edge, CBIR. 1. ful l w w, v,, p l w ƒwš. p ƒ w l w. z,,» v w š,» w ƒ y w š [1-4]. l»» (text-based image retrieval) ü» (content-based image retrieval) [5].» ü ƒ wš l l w ƒ w».» x wš ƒ. ù w w w. ü» ü e (color), (texture), (shape) ƒ p ü wš l l w p Corresponding Author Tel : japark@chosun.ac.kr w».»» w ƒ w w ƒ w w ƒ w š.. 2 f š g š w wš, 3 w f m w yw s w l w w. š 4 x š, s w s,,ƒ yw p y ü,, w. w m m j», s ƒ w y z w. v e œ w» w, y bin w v s ƒ w. e m f yw m w w š 45
