摘要: 针对MEPG-7主颜色描述符(DCD)无法反映色彩分布的空间信息这一缺陷,采用分块加权主颜色,并在分块加权主颜色的基础上,提出了相应的反馈方法。该反馈方法块间采用基于权重调整的关联反馈算法,块内采用调整主颜色特征值的方法。实验结果表明,该方法较好地解决了主颜色空间分布信息导致的误判,并且加入了相关反馈算法,提高了检索精度。

Abstract: In order to improve the defection performance of MEPG-7 Dominant Color Descriptor (DCD) that it is prone to lose the spatial information of colors, in this paper, blocks weighted dominant color descriptor was used, as well as the correlation feedback method was carried out. It used correlation feedback method to adjust weight value of the block and the dominant color feature in the block. Experimental results show that the method is much more effective than those based on only dominant colors and blocks dominant colors without feedback.

Key words: MPEG-7, image retrieval, relevance feedback, Dominant Color Descriptor (DCD), block weighting
