The Research Of Content Based Image Retrieve In Multimedia System

With the development of computer and its applications, image processing methods, video frequency technology and digital compresstechnology are rapidly developed. Kinds of information such as characters, images and sounds make up of multimedia system. Nowadays, multimedia systems are more and more applied into our lives and works, but there is a key issue, that is how to retrieve images efficiently and exactly, this "bottle-neck" 's solved will support further development of multimedia technology greatly.Content based image retrieve is one of current image retrieve methods, and a method researched most. Analyzed current image retrieve methods .using theories of Artificial Intelligence and integrating color and spatial information of image ,a new method is developed which is based on image content in this paper. This new intelligentized method could retrieve images efficiently and overcome current methods' shortcomings, and give developments of multimedia information systems very strong support.In this paper, some basic methods of image processing and how to use wavelet transform to pick up characteristics of images are introduced in detail and an new image retrieve method are given then, at the last, apply this new method to practical project, the retrieve results are satisfying.
