Image retrieval based on relevance feedback using blocks' weighted dominant colors in MPEG-7
XU Ye-qiang · Journal of Computer Applications · 2011
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.
