A spatial match representation scheme for indexing and querying in iconic image databases
Jae‐Woo Chang, Yeon-Jung Kim, Ki-Jin Chang · 1997
In multimedia information retrieval applications, contentbased image retrieval is essential for retrieving relevant mnltimedia documents.The purpose of our paper is to provide both effective representation and efficient retrieval of images when a pixel-level original image is antomaticahy or mannally transformed into its iconic image containing meaningful graphic descriptions, called icon objects.For this, we propose a new spatial match representation scheme to describe spatial relationships between icon objects preciseIy by using accurate positional operators as well as by expressing objects as rectangles, rather than pointer.In order to accelerate image searching, we also design an efficient retrieval method using a signature file technique.Finally, we show from our experiments that our representation scheme achieves better retrieval effectiveness than the 9-DLT scheme.Pm((ision 10 111nkl: di&l/lmd q&s OI';III or pa11 o(*(liis m;l(rri;d (i,r ~WSOI~~ W ChSSrtWlll USC IS g~nillllcd wi(hou( kc pvided (],a( (llc mpia .lrC11~1 mndc w dislrilwkul IiF pmli( or cwnmerci;tl ;)d\~l)(~g~e (lie cc,l,yrlf$l a(Niw.IIIC lilk ol'lht puhhca(ittn antI i(a d;t(c ;t(,p~:~r.:#lid a&y is #@II 1ll:ll LVp>Tlglll IS lly pmllision ol'llrc .\CB(.ltjc '('0 q+9 ~(l,cn,~ww (0 r~~Idlkh.10 IlOS1 WI .WlTCls or lo rcdis(rihu(c 10 lisls rq"irF s+yi(ic painiswln mid~or Lx,
