【摘要】 介绍了MPEG-7主颜色描述子、颜色布局描述子和边缘直方图描述子的提取方法和距离计算方法,提出一种综合运用主颜色描述子、颜色布局描述子和边缘直方图描述子进行图像检索的方法。实验结果证明,综合利用上述3种特征对图像进行描述及检索,可以获得比使用单一特征更好的检索效果。更多还原

【Abstract】 Extracting and matching algorithms for the dominant color descriptor,color layout descriptor and edge histogram descriptor suggested by MPEG7 are implemented and introduced in length.An image retrieval method which combines the three descriptors is proposed.The experiment shows that the results retrieved by the three descriptors are better than those retrieved by any single descriptor.更多还原
