【摘要】 分析现有的基于内容的图象检索系统局限性,提出一套基于MPEG-7标准的图象特征相关性检索新方案,在对通用模型进行概念化设计基础上,构建一种适合于图象组合特征检索的通用模型,利于图象特征相关性检索方程组的建立,快速自适应检索算法的高效实现,图象特征的内部归一化指标与外部归一化指标的综合描述,以及图象特征相关性权值系数的动态确定,实现内部图象特征标识与外部用户接口有机结合,提高基于内容的图象检索技术在Internet上的实用性。更多还原

【Abstract】 Based on analyzing the defects in content-based image retrieval systems for interrelation of image features,optimization model and generalization design,in this paper,refer to MPEG-7,a new scheme for interrelation retrieval of image features is set forth,and a conceptual design for optimizing the model is presented,which is propitious to the construction of interrelation retrieval equations and fast adaptive retrieval algorithm,the integrate description of inner unitary index together with external unitary index,and the dynamic confirmation of power coefficient among the different image features in the systems ,for the virtual combination of inner nameplate of image features and external interface in the systems ,and the practicability of content-based image retrieval method used for search engine on Internet.更多还原
