| 摘 要： | 提出多点多样性密度(MPDD)算法。针对经典多样性密度(DD)算法对样本包内容表述单一问题,采用多个密度点对包内容进行描述,避免了内容表述的片面性。将MPDD算法应用于图像检索。图像被均匀细分成小块,提取图像的颜色特征和纹理特征表示图像块内容,然后采用K均值算法对实现图像块进行聚类,产生包示例,最后应用MPDD算法对图像进行检索。实验结果表明,MPDD算法的检索效果好于DD算法。 |

| Abstract: | A Multi-Points Diverse Density(MPDD) learning algorithm was proposed.In classical diverse density learning algorithm,only one point was used to represent the content of bags,which was not enough.In the proposed MPDD learning algorithm,multi-points were utilized to contain more information.This algorithm was applied to image retrieval.First,an image was divided into small blocks,and the color and texture features of these small blocks were extracted to describe the content of an image block.Then,K-means algo... |
