Abstract: The study addressed the problems of present image database with incomplete image semantics, no-unified content description standard and no security, in which images is independent of DBMS. The content architecture of imarge database was determined with lower features such as color, texture, shape etc, middle object and higher emotion. The Mpeg-7 based multi-layer semantic description framework was proposed because of the modification and expansion of Mpeg-7. A multi-layer semantics image database with 188 images was established using ORDB multi-media database implementation techniques in Oracle9i. Theoretical analysis and experimental results shows the distinctive superiority of the image database itself.
