| 摘要: |
| 结合MPEG-7的颜色与形状两种描述符设计出了一个新的图像检索系统,利用MPEG-7提供的主颜色描述符及基于区域的形状描述算法--角放射变换(ART)对图像进行特征提取、描述.实验用MPEG-7的评价准则进行评判,由包括花卉、自然风景及商标组成的图像库进行测试,结果表明,综合这两种特征进行检索比使用单一特征取得的检索效果更佳. |

| Abstract: |
| A new image retrieval system based on MPEG-7 is designed.The main color descriptor is used to extract the color feature of the image,and a region base shape descriptor,the Angular Radial Transform (ART),is used to extract the shape feature of the image.The experiment evaluation criterion used is given by MPEG-7,and image library including flowers,natural scenery and trademark are used to test.The result of the image retrieval system combining two descriptors is superior to that obtained from single feature. |
| Key words: image retrieval,MPEG-7,color feature,shape feature,angular radial transform(ART) |
