Image Retrieval Based on Color Saliency Histogram
Yunqi Lei, Zhenxiang Shi, Xutuan Jiang, Qingmin Li, Dongjie Chen · 2009
A new image retrieval method based on color saliency histogram is proposed. Two features of a given image, the radius entropy and angle entropy, are defined and used to describe the spatial distribution of color, then, combining the entropies with the color coherence value, the saliency of each kind of color is calculated. After that, the color saliency histogram is built for image retrieval. Experimental results show that the proposed method is feasible and more effective.
