基于颜色特征的图像检索技术的分析和实现

随着计算机技术和Internet网络的发展,信息数量和信息媒体种类在不断增加,而图像信息更是目前得到的最直观和数量最多的信息之一。数据库是各类信息管理系统的核心部分之一,图像检索技术结合了图像自身所含的特征以及数据库技术,是一项在理论研究和实际应用中都极有前途的新技术。在分析颜色检索的算法的基础上,给出一种基于对称色彩空域特征的同心圆划分图像匹配算法,通过引入对称的空域信息,最终达到提高图像检索的准确性。

Analysis and Implementation of Color- based Image Retrieval Technology

With the development of computer and Internet network technology,the quantity and category of information grow continuously.The information of image is one of most intuitionistic and amount of them.The database is the core of all kinds of system of information management.The technology of image retrieval combine the database and the character of image itself,which is a new and evolutive technology either in the academic research and actual application.In this article,based on the algorithm of color-based is analyzed,a concentric circles of the image matching algorithm is given,which is based on the symmetry features of color space.By introducing symmetrical space information,the accuracy of image retrieval is achieved.
