【摘要】 随着计算机自身以及计算机应用技术的发展,图像处理技术、视频技术、数字压缩技术等都得到了迅猛的发展。文字、图像和语言等多种信息形式构成了多媒体系统。目前,多媒体系统已经越来越多地被应用到人们生活和工作的多个领域。但多媒体技术中的一个关键问题是如何对大量的图像信息进行高效、准确的检索,解决了这一“瓶颈”问题,对多媒体技术的进一步发展将有巨大的推动作用。 基于内容的图像检索(CBIR)是现有的图像检索方法中的一种,同时也是目前研究最多的一种方法。本文在分析了现有的基于内容的图像检索方法后,利用人工智能原理,将图像中的色彩信息、空间信息集成起来,提出了一种基于内容的、智能化的集成色彩空间的图像检索方法。这种方法能有效地完成对图像的检索,克服以往图像检索技术的弱点,实现智能化的检索,为多媒体信息系统的开发提供了有力的支持。 本文先详细介绍了图像处理的一些基本方法和利用小波变换的方法来提取图像的特征,然后提出了一种新的基于内容的图像检索方法,最后将提出的这种智能化的集成色彩空间的图像检索方法应用到实际的工程项目中,取得了令人满意的图像检索效果。

【Abstract】 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.
