基于形状特征的图像检索系统的设计

基于图像形状特征的图像检索方法已成为一个研究热点。为了便于在众多的图像信息库中快速、准确的检索出所需图像，研究了基于形状特征图像检索的主要步骤，且对步骤中所涉及的算法做了比较、选取、改进。利用MATLAB语言开发了一个基于形状特征的图像检索系统。并对该系统进行了测试，通过测试表明该系统可以有效的检索出相似的图像，且对于实验结果做了查全率和查准率的计算与分析，结果证明该系统切实可行具有一定的推广价值和使用价值。

Image retrieval and classification based on shape feature

The image retrieval based on shape feature has become a hot research topic. In order to facilitate to retrieve image rapidly and accurately among the numerous image information, the major steps of image retrieval based on the shape feature have been researched in this paper. Still the algorithms involved in the steps have been compared, selected and improved. A system of the image retrieval based on the shape feature is developed in MATLAB. It is tested that the system can effectively retrieve similar images. And the experimental results of calculation and analysis of the precision and recall rate, the result proves that the system is feasible and has a certain popularization value and use value.
