Image retrieval method combining integer and blocks'''' color distribution
融合整体与分块颜色分布的图像检索方法

In order to overcome the defect that the conventional color histogram retrieval method is prone to lose the spatial information of colors, an image retrieval method based on the largest color-connected regions was presented, and its rim roughness to capture the regional traits and reduce the absolute dependence on color. Then the similarity of the images is defined as the combination of the similarity of an integer and the similarity of the blocks to reflect the recognition process by people. The experimental result on real-world image collections indicates that the proposed approach significantly improves image retrieval accuracy.
