Abstract: This paper presents an algorithm to extract the image characteristics by using the techniques of wavelet analysis and embedded zerotreewavelet coding. The indexing of traditional database and content-based retrieval technologies are adopted together with the supporting of oracle8i onthe aspect of visual retrieval information. Experiments prove that this method is effective and enhances the performance of traditional database onimage retrieval.
