摘    要:本文以国家发改委CNGI项目“基于IPv6的广播影视资料P2P内容存取中闾件系统”为背景,研究了基于内容的图像检索技术。通过对常用颜色和纹理特征提取算法的研究,选择了块RGB均值法、改进参考颜色表法和灰度一平滑共生矩阵法对图像进行特征提取,并使用标准的Corel库建立图像特征数据库,分析和比较这几秤算法单独检索和综合检索的效果。实验结果证明,采用多特征的综合检索比采用单特征的检索具有更高的查全率和查准率,因此采用综合特征检索技术,能够更好地实现对广播影视资料的内容检索。

关 键 词:图像检索  颜色  纹理

Abstract:The broadcasting & film P2P content extraction middleware system based on IPv6 is a China Next Generation Internet project of National Development and Reform Commission.On the background of this project,the content based image retrieval is studied.The normal color and texture feature extraction algorithm is mainly researched.Choose the block RGB means method,advanced reference color table and grey smooth co occurrence matrix to extract the features from images.The standard Corel image library is used to set up the image feature database.In this paper,not only one single feature is used to retrieve images,but also combined-feature is used to retrieve.And the result is analyzed.Lots of experiments prove that the retrieval result gaining from combined-feature is more efficient.The recall and precision is improved.So the combinedfeature is used to retrieve the broadcasting & film images.
Keywords:image retrieval   color   texture
